Learn more about the features listed here through the provided links or from the list on <a href="https://www.chromestatus.com/features#milestone%3D76">ChromeStatus.com</a>. Chrome 86 is beta as of September 3, 2020.</p> <h2>CSS Pseudo-Class: focus-visible and the Quick Focus Highlight</h2> <p>For users who rely on a keyboard or similar assistive technology to navigate the web, the focus indicator is a crucial visual affordance. To improve both the user and developer experience of working with focus, Chrome 86 is introducing two features.</p> <p>The first is a CSS selector, <span style="font-family: courier;">:focus-visible</span>, which lets a developer opt-in to the same heuristic the browser uses when it's deciding whether to display a default focus indicator.</p> <p>The second is a user setting called Quick Focus Highlight. When enabled, this setting causes an additional focus indicator to appear over the active element. Importantly, this indicator will be visible even if the page has disabled focus styles with CSS and it causes any <span style="font-family: courier;">:focus</span> or <span style="font-family: courier;">:focus-visible</span> styles to always be displayed. For details, see <a href="https://blog.chromium.org/2020/09/giving-users-and-developers-more.html">Giving users and developers more control over focus</a>.</p> <p><img alt="An animation of the quick focus highlight showing how it temporarily highlights a link in a line of text and then fades out to not obscure the text content." height="300" src="https://lh3.googleusercontent.com/wdnRyP2HviHI6UiFh-aCkVzNGzk0NWouNBV5ELT7nT8dXFi1jbnSGPFygFpgjZFU89SI7_rXrgsUrg6OoUMHUsedyduot403v1t1vkZuStYZ-yYroHCUFi0ZXfChKUiFSQUWslJE9w" style="margin-left: 0px; margin-top: 0px;" width="624" /></p> <h2>WebHID API</h2> <p><strong>Note:</strong> The origin trial for this feature was originally announced as starting in Chrome 85. That timeline changed.</p> <p>There is a long tail of human interface devices (HIDs) that are too new, too old, or too uncommon to be accessible by systems' device drivers. The WebHID API solves this by providing a way to implement device-specific logic in JavaScript. </p> <p>An HID is one that takes input from or provides output to humans. Examples of devices include keyboards, pointing devices (mice, touchscreens, etc.), and gamepads.</p> <p>The inability to access uncommon or unusual HID devices is particularly painful when it comes to gamepad support. Gamepad inputs and outputs are not well standardized and web browsers often require custom logic for specific devices. This is unsustainable and results in poor support for the long tail of older and uncommon devices.</p> <p>We're working on an article to show you how to use the new API. In the meantime, we've found some demos from a few eager engineers that you can use to try the new API. To see those demos, check out <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/6731598246400651105#">Human interface devices on the web: a few quick examples</a>. The <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/6731598246400651105#">Origin Trials section</a> has information on signing up and a list of other origin trials starting in this release. This origin trial is expected to run through Chrome 87 in January 2021.</p> <h2>Origin Trials</h2> <p>This version of Chrome introduces the origin trials described below. Origin trials allow you to try new features and give feedback on usability, practicality, and effectiveness to the web standards community. To register for any of the origin trials currently supported in Chrome, including the ones described below, visit the <a href="https://developers.chrome.com/origintrials/#/trials/active">Origin Trials dashboard</a>. To learn more about origin trials themselves, visit the <a href="https://github.com/GoogleChrome/OriginTrials/blob/gh-pages/developer-guide.md">Origin Trials Guide for Web Developers</a>.</p> <h3>New Origin Trials</h3> <h4>Cross-Screen Window Placement</h4> <p>Adds new <a href="https://developers.chrome.com/origintrials/#/view_trial/1411878483180650497">screen information APIs</a> and makes incremental improvements to existing window placement APIs, allowing web applications to offer compelling multi-screen experiences. </p> <p>The existing <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/screen">window.screen property</a> offers a limited view of available screen space, while window placement functions are generally restricted to the current screen. This feature unlocks modern multi-screen capabilities for web applications.</p> <h4>battery-savings Meta Tag</h4> <p><a href="https://developers.chrome.com/origintrials/#/view_trial/4114038259602948097">Adds a meta tag</a> allowing a site to recommend measures for the user agent to apply in order to save battery life and optimize CPU usage. Websites that are known to have high CPU or battery costs may want to request that the UA optimize for CPU or battery, even if the user has not requested it. Most modern operating systems also have battery saving features that activate either when the battery is low or the user wishes to save battery. Ideally web sites should be able to respect these settings. Sites may wish to advise the user agent on which strategies work best for the site in these situations.</p> <h4>Secure Payment Confirmation</h4> <p><a href="https://developers.chrome.com/origintrials/#/view_trial/42784196460019713">Secure payment confirmation</a> augments the payment authentication experience on the web with the help of the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API">Web Authentication API</a>. The feature adds a new <span style="font-family: courier;">PaymentCredential</span> credential type to the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Credential_Management_API">Credential Management API</a>, which allows a relying party such as a bank to create a <span style="font-family: courier;">PublicKeyCredential</span> that can be queried by any merchant origin as part of an online checkout via the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Payment_Request_API">Payment Request API</a> using the proposed secure-payment-confirmation payment method.</p> <p>This feature enables a consistent, low friction, strong authentication experience using platform authenticators. Strong authentication with the user's bank is becoming a requirement for online payments in many regions, including the European Union. The new feature provides a better user experience and stronger security than existing solutions.</p> <h4>Cross-Origin-Opener-Policy Reporting API</h4> <p>Adds a reporting API to <a href="https://developers.chrome.com/origintrials/#/view_trial/2780972769901281281">help developers deploy cross-origin opener policy</a> (COOP) on their websites. In addition to reporting breakages when COOP is enforced, it proves a report-only mode that reports potential breakages that would have happened had COOP been enforced. To register for the origin trial, follow the link above. For more information, see <a href="https://web.dev/coop-coep/">Making your website "cross-origin isolated" using COOP and COEP</a>.</p> <h3>Completed Origin Trials</h3> <p>The following features, previously in a Chrome origin trial, are now enabled by default.</p> <h4>Native File System</h4> <p>The new Native File System API enables developers to build powerful web apps that interact with files on the user's local device such as IDEs, photo and video editors, text editors, and more. After a user grants access, this API allows web apps to read or save changes directly to files and folders on the user's device. It does all this by invoking the platform's own open and save dialog boxes. The image below shows a web page invoked using the open dialog box on Mac.</p> <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKvel8L36VOa_0TJ-XZqGa1XunSXfUmCrzM9m5hSQpQLzvn4EXrsgwW0ZjUqlIk59AWgLWQw8J1wzfLfHKVMkygNMVlUPlwWs61ACTRgALdCnpckldA7kmRVErDxfUQ0IdwjBJG0iUVldM/s1081/native-file-system.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="780" data-original-width="1081" height="462" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKvel8L36VOa_0TJ-XZqGa1XunSXfUmCrzM9m5hSQpQLzvn4EXrsgwW0ZjUqlIk59AWgLWQw8J1wzfLfHKVMkygNMVlUPlwWs61ACTRgALdCnpckldA7kmRVErDxfUQ0IdwjBJG0iUVldM/w640-h462/native-file-system.png" width="640" /></a></div> <p>To learn more, see sample code, and a text editor demonstration app, see <a href="https://web.dev/native-file-system/">The Native File System API: Simplifying access to local files</a> for details.</p> <p><strong>Note:</strong> The API surface is changed considerably from what was available in the origin trial. Differences are <a href="https://github.com/WICG/native-file-system/blob/master/changes.md">explained in detail</a> in the spec repo. In the coming weeks, watch the web.dev article listed above for a full explanation of how to use the production version of the API. </p> <h2>Other Features in This Release</h2> <h3>Altitude and Azimuth for PointerEvents v3</h3> <p><a href="https://www.chromestatus.com/feature/5731966710185984">Adds <span style="font-family: courier;">Altitude</span> and <span style="font-family: courier;">Azimuth</span> angles to <span style="font-family: courier;">PointerEvents</span></a>. Adds <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> to <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span> transformation and altitude and azimuth to <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> transformation depending on which pair is available from the device. These angles are those commonly measured by devices. Altitude and azimuth can be calculated using trigonometry from <span style="font-family: courier;">tiltX</span>, <span style="font-family: courier;">tiltY</span>. From a hardware perspective it is easier and less expensive to measure <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span>.</p><p>From a stylus app perspective <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span> makes more sense and is more intuitive for users. Using <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> requires a developer to visualize the intersection angle between two imaginary planes, while <span style="font-family: courier;">azimuth</span> and <span style="font-family: courier;">altitude</span> are easier to visualize just by looking at the pen and the screen surface.</p><p>Adding <span style="font-family: courier;">azimuth</span> and <span style="font-family: courier;">altitude</span> makes the API more intuitive. Providing conversion between <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> and <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span> and vice versa allows for backwards compatibility with apps using <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> (even if newer devices might only return <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span>).</p><h3 style="text-align: left;">A Well-Known URL for Changing Passwords</h3><div><b>Note: </b>this was erroneously listed as shipping in Chrome 86. It is actually shipping in Chrome 87.</div><p>Websites can set <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/5647775477348732729#">a well-known URL for changing passwords</a> (for example, <span style="font-family: courier;">/.well-known/change-password</span>). This URL's purpose is to redirect users to the change password page in order for them to modify their passwords quickly. Chrome leverages this URL to help users change their passwords when it detects a saved, compromised password. For more information, see <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/5647775477348732729#">Help users change passwords easily by adding a well-known URL for changing passwords</a>.</p> <h3>Change Encoding of Space Character when URLs are Computed by Custom Protocol Handlers</h3> <p>The <span style="font-family: courier;">navigator.registerProtocolHandler()</span> handler <a href="https://www.chromestatus.com/feature/5678518908223488">now replaces spaces</a> with "%20" instead of "+". This makes Chrome consistent with other browsers such as Firefox. </p> <h3>CSS ::marker Pseudo-Element</h3> <p>Adds <a href="https://web.dev/css-marker-pseudo-element/">a pseudo-element for customizing numbers and bullets</a> for <span style="font-family: courier;"><ul></span> and <span style="font-family: courier;"><ol></span> elements. This change lets developers control the color, size, bullet shape, and number type.</p> <h3>Document-Policy Header</h3> <p><a href="https://www.chromestatus.com/feature/5756689661820928">Document Policy</a> restricts the surface area of the web platform on a per-document basis, similar to iframe sandboxing, but more flexibly. It can do things like:</p> <ul> <li>Restrict the use of poorly-performing images.</li> <li>Disable slow synchronous JavaScript APIs.</li> <li>Configure iframe, image, or script loading styles.</li> <li>Restrict overall document sizes or network usage.</li> <li>Restrict patterns which cause page re-layout.</li> </ul> <p>Additionally, the header allows sites to opt out of fragment and text-fragment scrolling on load as a privacy mitigation for the scroll-to-text-fragment feature. This is the first part of the Document Policy API to ship. </p> <h3>EME persistent-usage-record Session</h3> <p>Adds <a href="https://www.chromestatus.com/feature/5638708017496064">a new <span style="font-family: courier;">MediaKeySessionType</span></a> named <span style="font-family: courier;">"persistent-usage-record session"</span>, for which the license and keys are not persisted and for which a record of key usage is persisted when the keys available within the session are destroyed. This feature may help content providers understand how decryption keys are used for purposes like fraud detection.</p> <h3>FetchEvent.handled</h3> <p>A <span style="font-family: courier;">FetchEvent</span> dispatched to a service worker is in a loading pipeline, which is performance sensitive. The new <a href="https://www.chromestatus.com/feature/5654467158474752"><span style="font-family: courier;">FetchEvent.handled</span> property</a> returns a promise that resolves when a response is returned from a service worker to its client. This enables a service worker to delay tasks that can only run after responses are complete. </p> <h3>HTMLMediaElement.preservesPitch</h3> <p>Adds a property to determine whether the pitch of an audio or video element should be <a href="https://www.chromestatus.com/feature/5742134990733312">preserved when adjusting the playback rate</a>. This feature is wanted for creative purposes (for example, pitch-shifting in "DJ deck" style applications). It also prevents the introduction of artifacts from pitch-preserving algorithms at playback speeds very close to 1.00.

Visit ChromeStatus.com for lists of <a href="https://www.chromestatus.com/features#browsers.chrome.status%3A%22Deprecated%22">current deprecations</a> and <a href="https://www.chromestatus.com/features#browsers.chrome.status:%22Removed%22">previous removals</a>.</p> <h3>Remove WebComponents v0 from WebView</h3> <p>Web Components v0 was removed from desktop and Android in Chrome 80. Chromium 86 removes them from WebView. This removal includes <a href="https://www.chromestatus.com/feature/4642138092470272">Custom Elements v0</a>, <a href="https://www.chromestatus.com/feature/4507242028072960">Shadow DOM v0</a>, and <a href="https://www.chromestatus.com/feature/5144752345317376">HTML Imports</a>.</p> <h3>Deprecate FTP Support</h3> <p>Chrome is deprecating and removing support for FTP URLs. The current FTP implementation in Google Chrome has no support for encrypted connections (FTPS), or proxies. Usage of FTP in the browser is sufficiently low that it is no longer viable to invest in improving the existing FTP client. In addition, more capable FTP clients are available on all affected platforms.</p> <p>Chrome 72 and later removed support for fetching document subresources over FTP and rendering of top level FTP resources. Currently navigating to FTP URLs results in showing a directory listing or a download depending on the type of resource. A bug in Google Chrome 74 and later resulted in dropping support for accessing FTP URLs over HTTP proxies. Proxy support for FTP was removed entirely in Google Chrome 76.</p> <p>The remaining capabilities of Google Chrome's FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections. </p> <p>Deprecation of support will follow this timeline:</p> <h4>Chrome 86</h4> <p>FTP is still enabled by default for most users, but turned off for pre-release channels (Canary and Beta) and will be experimentally turned off for one percent of stable users. In this version you can re-enable it from the command line using either the <span style="font-family: courier;">--enable-ftp</span> command line flag or the <span style="font-family: courier;">--enable-features=FtpProtocol</span> flag.</p> <h4>Chrome 87</h4> <p>FTP support will be disabled by default for fifty percent of users but can be enabled using the flags listed above.</p> <h4>Chrome 88</h4> <p>FTP support will be disabled.</p> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <p>Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on <a href="https://www.chromestatus.com/features#milestone%3D76">ChromeStatus.com</a>. Chrome 86 is beta as of September 3, 2020.</p> <h2>CSS Pseudo-Class: focus-visible and the Quick Focus Highlight</h2> <p>For users who rely on a keyboard or similar assistive technology to navigate the web, the focus indicator is a crucial visual affordance. To improve both the user and developer experience of working with focus, Chrome 86 is introducing two features.</p> <p>The first is a CSS selector, <span style="font-family: courier;">:focus-visible</span>, which lets a developer opt-in to the same heuristic the browser uses when it's deciding whether to display a default focus indicator.</p> <p>The second is a user setting called Quick Focus Highlight. When enabled, this setting causes an additional focus indicator to appear over the active element. Importantly, this indicator will be visible even if the page has disabled focus styles with CSS and it causes any <span style="font-family: courier;">:focus</span> or <span style="font-family: courier;">:focus-visible</span> styles to always be displayed. For details, see <a href="https://blog.chromium.org/2020/09/giving-users-and-developers-more.html">Giving users and developers more control over focus</a>.</p> <p><img alt="An animation of the quick focus highlight showing how it temporarily highlights a link in a line of text and then fades out to not obscure the text content." height="300" src="https://lh3.googleusercontent.com/wdnRyP2HviHI6UiFh-aCkVzNGzk0NWouNBV5ELT7nT8dXFi1jbnSGPFygFpgjZFU89SI7_rXrgsUrg6OoUMHUsedyduot403v1t1vkZuStYZ-yYroHCUFi0ZXfChKUiFSQUWslJE9w" style="margin-left: 0px; margin-top: 0px;" width="624" /></p> <h2>WebHID API</h2> <p><strong>Note:</strong> The origin trial for this feature was originally announced as starting in Chrome 85. That timeline changed.</p> <p>There is a long tail of human interface devices (HIDs) that are too new, too old, or too uncommon to be accessible by systems' device drivers. The WebHID API solves this by providing a way to implement device-specific logic in JavaScript. </p> <p>An HID is one that takes input from or provides output to humans. Examples of devices include keyboards, pointing devices (mice, touchscreens, etc.), and gamepads.</p> <p>The inability to access uncommon or unusual HID devices is particularly painful when it comes to gamepad support. Gamepad inputs and outputs are not well standardized and web browsers often require custom logic for specific devices. This is unsustainable and results in poor support for the long tail of older and uncommon devices.</p> <p>We're working on an article to show you how to use the new API. In the meantime, we've found some demos from a few eager engineers that you can use to try the new API. To see those demos, check out <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/6731598246400651105#">Human interface devices on the web: a few quick examples</a>. The <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/6731598246400651105#">Origin Trials section</a> has information on signing up and a list of other origin trials starting in this release. This origin trial is expected to run through Chrome 87 in January 2021.</p> <h2>Origin Trials</h2> <p>This version of Chrome introduces the origin trials described below. Origin trials allow you to try new features and give feedback on usability, practicality, and effectiveness to the web standards community. To register for any of the origin trials currently supported in Chrome, including the ones described below, visit the <a href="https://developers.chrome.com/origintrials/#/trials/active">Origin Trials dashboard</a>. To learn more about origin trials themselves, visit the <a href="https://github.com/GoogleChrome/OriginTrials/blob/gh-pages/developer-guide.md">Origin Trials Guide for Web Developers</a>.</p> <h3>New Origin Trials</h3> <h4>Cross-Screen Window Placement</h4> <p>Adds new <a href="https://developers.chrome.com/origintrials/#/view_trial/1411878483180650497">screen information APIs</a> and makes incremental improvements to existing window placement APIs, allowing web applications to offer compelling multi-screen experiences. </p> <p>The existing <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/screen">window.screen property</a> offers a limited view of available screen space, while window placement functions are generally restricted to the current screen. This feature unlocks modern multi-screen capabilities for web applications.</p> <h4>battery-savings Meta Tag</h4> <p><a href="https://developers.chrome.com/origintrials/#/view_trial/4114038259602948097">Adds a meta tag</a> allowing a site to recommend measures for the user agent to apply in order to save battery life and optimize CPU usage. Websites that are known to have high CPU or battery costs may want to request that the UA optimize for CPU or battery, even if the user has not requested it. Most modern operating systems also have battery saving features that activate either when the battery is low or the user wishes to save battery. Ideally web sites should be able to respect these settings. Sites may wish to advise the user agent on which strategies work best for the site in these situations.</p> <h4>Secure Payment Confirmation</h4> <p><a href="https://developers.chrome.com/origintrials/#/view_trial/42784196460019713">Secure payment confirmation</a> augments the payment authentication experience on the web with the help of the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API">Web Authentication API</a>. The feature adds a new <span style="font-family: courier;">PaymentCredential</span> credential type to the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Credential_Management_API">Credential Management API</a>, which allows a relying party such as a bank to create a <span style="font-family: courier;">PublicKeyCredential</span> that can be queried by any merchant origin as part of an online checkout via the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Payment_Request_API">Payment Request API</a> using the proposed secure-payment-confirmation payment method.</p> <p>This feature enables a consistent, low friction, strong authentication experience using platform authenticators. Strong authentication with the user's bank is becoming a requirement for online payments in many regions, including the European Union. The new feature provides a better user experience and stronger security than existing solutions.</p> <h4>Cross-Origin-Opener-Policy Reporting API</h4> <p>Adds a reporting API to <a href="https://developers.chrome.com/origintrials/#/view_trial/2780972769901281281">help developers deploy cross-origin opener policy</a> (COOP) on their websites. In addition to reporting breakages when COOP is enforced, it proves a report-only mode that reports potential breakages that would have happened had COOP been enforced. To register for the origin trial, follow the link above. For more information, see <a href="https://web.dev/coop-coep/">Making your website "cross-origin isolated" using COOP and COEP</a>.</p> <h3>Completed Origin Trials</h3> <p>The following features, previously in a Chrome origin trial, are now enabled by default.</p> <h4>Native File System</h4> <p>The new Native File System API enables developers to build powerful web apps that interact with files on the user's local device such as IDEs, photo and video editors, text editors, and more. After a user grants access, this API allows web apps to read or save changes directly to files and folders on the user's device. It does all this by invoking the platform's own open and save dialog boxes. The image below shows a web page invoked using the open dialog box on Mac.</p> <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKvel8L36VOa_0TJ-XZqGa1XunSXfUmCrzM9m5hSQpQLzvn4EXrsgwW0ZjUqlIk59AWgLWQw8J1wzfLfHKVMkygNMVlUPlwWs61ACTRgALdCnpckldA7kmRVErDxfUQ0IdwjBJG0iUVldM/s1081/native-file-system.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="780" data-original-width="1081" height="462" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKvel8L36VOa_0TJ-XZqGa1XunSXfUmCrzM9m5hSQpQLzvn4EXrsgwW0ZjUqlIk59AWgLWQw8J1wzfLfHKVMkygNMVlUPlwWs61ACTRgALdCnpckldA7kmRVErDxfUQ0IdwjBJG0iUVldM/w640-h462/native-file-system.png" width="640" /></a></div> <p>To learn more, see sample code, and a text editor demonstration app, see <a href="https://web.dev/native-file-system/">The Native File System API: Simplifying access to local files</a> for details.</p> <p><strong>Note:</strong> The API surface is changed considerably from what was available in the origin trial. Differences are <a href="https://github.com/WICG/native-file-system/blob/master/changes.md">explained in detail</a> in the spec repo. In the coming weeks, watch the web.dev article listed above for a full explanation of how to use the production version of the API. </p> <h2>Other Features in This Release</h2> <h3>Altitude and Azimuth for PointerEvents v3</h3> <p><a href="https://www.chromestatus.com/feature/5731966710185984">Adds <span style="font-family: courier;">Altitude</span> and <span style="font-family: courier;">Azimuth</span> angles to <span style="font-family: courier;">PointerEvents</span></a>. Adds <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> to <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span> transformation and altitude and azimuth to <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> transformation depending on which pair is available from the device. These angles are those commonly measured by devices. Altitude and azimuth can be calculated using trigonometry from <span style="font-family: courier;">tiltX</span>, <span style="font-family: courier;">tiltY</span>. From a hardware perspective it is easier and less expensive to measure <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span>.</p><p>From a stylus app perspective <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span> makes more sense and is more intuitive for users. Using <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> requires a developer to visualize the intersection angle between two imaginary planes, while <span style="font-family: courier;">azimuth</span> and <span style="font-family: courier;">altitude</span> are easier to visualize just by looking at the pen and the screen surface.</p><p>Adding <span style="font-family: courier;">azimuth</span> and <span style="font-family: courier;">altitude</span> makes the API more intuitive. Providing conversion between <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> and <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span> and vice versa allows for backwards compatibility with apps using <span style="font-family: courier;">tiltX</span> and <span style="font-family: courier;">tiltY</span> (even if newer devices might only return <span style="font-family: courier;">altitude</span> and <span style="font-family: courier;">azimuth</span>).</p><h3 style="text-align: left;">A Well-Known URL for Changing Passwords</h3><div><b>Note: </b>this was erroneously listed as shipping in Chrome 86. It is actually shipping in Chrome 87.</div><p>Websites can set <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/5647775477348732729#">a well-known URL for changing passwords</a> (for example, <span style="font-family: courier;">/.well-known/change-password</span>). This URL's purpose is to redirect users to the change password page in order for them to modify their passwords quickly. Chrome leverages this URL to help users change their passwords when it detects a saved, compromised password. For more information, see <a href="https://www.blogger.com/blog/post/edit/2471378914199150966/5647775477348732729#">Help users change passwords easily by adding a well-known URL for changing passwords</a>.</p> <h3>Change Encoding of Space Character when URLs are Computed by Custom Protocol Handlers</h3> <p>The <span style="font-family: courier;">navigator.registerProtocolHandler()</span> handler <a href="https://www.chromestatus.com/feature/5678518908223488">now replaces spaces</a> with "%20" instead of "+". This makes Chrome consistent with other browsers such as Firefox. </p> <h3>CSS ::marker Pseudo-Element</h3> <p>Adds <a href="https://web.dev/css-marker-pseudo-element/">a pseudo-element for customizing numbers and bullets</a> for <span style="font-family: courier;"><ul></span> and <span style="font-family: courier;"><ol></span> elements. This change lets developers control the color, size, bullet shape, and number type.</p> <h3>Document-Policy Header</h3> <p><a href="https://www.chromestatus.com/feature/5756689661820928">Document Policy</a> restricts the surface area of the web platform on a per-document basis, similar to iframe sandboxing, but more flexibly. It can do things like:</p> <ul> <li>Restrict the use of poorly-performing images.</li> <li>Disable slow synchronous JavaScript APIs.</li> <li>Configure iframe, image, or script loading styles.</li> <li>Restrict overall document sizes or network usage.</li> <li>Restrict patterns which cause page re-layout.</li> </ul> <p>Additionally, the header allows sites to opt out of fragment and text-fragment scrolling on load as a privacy mitigation for the scroll-to-text-fragment feature. This is the first part of the Document Policy API to ship. </p> <h3>EME persistent-usage-record Session</h3> <p>Adds <a href="https://www.chromestatus.com/feature/5638708017496064">a new <span style="font-family: courier;">MediaKeySessionType</span></a> named <span style="font-family: courier;">"persistent-usage-record session"</span>, for which the license and keys are not persisted and for which a record of key usage is persisted when the keys available within the session are destroyed. This feature may help content providers understand how decryption keys are used for purposes like fraud detection.</p> <h3>FetchEvent.handled</h3> <p>A <span style="font-family: courier;">FetchEvent</span> dispatched to a service worker is in a loading pipeline, which is performance sensitive. The new <a href="https://www.chromestatus.com/feature/5654467158474752"><span style="font-family: courier;">FetchEvent.handled</span> property</a> returns a promise that resolves when a response is returned from a service worker to its client. This enables a service worker to delay tasks that can only run after responses are complete. </p> <h3>HTMLMediaElement.preservesPitch</h3> <p>Adds a property to determine whether the pitch of an audio or video element should be <a href="https://www.chromestatus.com/feature/5742134990733312">preserved when adjusting the playback rate</a>. This feature is wanted for creative purposes (for example, pitch-shifting in "DJ deck" style applications). It also prevents the introduction of artifacts from pitch-preserving algorithms at playback speeds very close to 1.00. It is already supported by Safari and Firefox. </p> <h3>Imperative Shadow DOM Distribution API</h3> <p>Web developers can now <a href="https://www.chromestatus.com/feature/5711021289242624">explicitly set the assigned nodes</a> for a slot element. This solves two problems with Shadow DOM v1:</p> <ul> <li>Web developers must specify a slot attribute for every one of a shadow host's children (except for elements for the default slot).</li> <li>Component creators can't change the slotting behavior based on conditions.</li> </ul> <p>For information on how the new API solves these issues, see the <a href="https://github.com/w3c/webcomponents/blob/gh-pages/proposals/Imperative-Shadow-DOM-Distribution-API.md">Imperative Shadow DOM Distribution API explainer</a>.</p> <h3>Move window.location.fragmentDirective</h3> <p>The <span style="font-family: courier;">window.location.fragmentDirective</span> property <a href="https://www.chromestatus.com/feature/5679640498667520">has been moved</a> to <span style="font-family: courier;">document.fragmentDirective</span>.

This removal includes <a href="https://www.chromestatus.com/feature/4642138092470272">Custom Elements v0</a>, <a href="https://www.chromestatus.com/feature/4507242028072960">Shadow DOM v0</a>, and <a href="https://www.chromestatus.com/feature/5144752345317376">HTML Imports</a>.</p> <h3>Deprecate FTP Support</h3> <p>Chrome is deprecating and removing support for FTP URLs. The current FTP implementation in Google Chrome has no support for encrypted connections (FTPS), or proxies. Usage of FTP in the browser is sufficiently low that it is no longer viable to invest in improving the existing FTP client. In addition, more capable FTP clients are available on all affected platforms.</p> <p>Chrome 72 and later removed support for fetching document subresources over FTP and rendering of top level FTP resources. Currently navigating to FTP URLs results in showing a directory listing or a download depending on the type of resource. A bug in Google Chrome 74 and later resulted in dropping support for accessing FTP URLs over HTTP proxies. Proxy support for FTP was removed entirely in Google Chrome 76.</p> <p>The remaining capabilities of Google Chrome's FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections. </p> <p>Deprecation of support will follow this timeline:</p> <h4>Chrome 86</h4> <p>FTP is still enabled by default for most users, but turned off for pre-release channels (Canary and Beta) and will be experimentally turned off for one percent of stable users. In this version you can re-enable it from the command line using either the <span style="font-family: courier;">--enable-ftp</span> command line flag or the <span style="font-family: courier;">--enable-features=FtpProtocol</span> flag.</p> <h4>Chrome 87</h4> <p>FTP support will be disabled by default for fifty percent of users but can be enabled using the flags listed above.</p> <h4>Chrome 88</h4> <p>FTP support will be disabled.</p> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Chromium Blog:Chrome 86: Improved Focus Highlighting, WebHID, and More&url=https://blog.chromium.org/2020/09/chrome-86-improved-focus-highlighting.html&via=ChromiumDev'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://blog.chromium.org/2020/09/chrome-86-improved-focus-highlighting.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://blog.chromium.org/2020/09/chrome-86-improved-focus-highlighting.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://blog.chromium.org/search/label/beta' rel='tag'> beta </a> </span> </div> </div> </div> <div class='post' data-id='3237315285382505488' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://blog.chromium.org/2020/09/giving-users-and-developers-more.html' itemprop='url' title='Giving users and developers more control over focus'> Giving users and developers more control over focus </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Wednesday, September 2, 2020 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> <style> .code-block { font-family: monospace; font-size: 14px; color: #000; overflow-x: scroll; } </style> <span id="docs-internal-guid-467d89b6-7fff-a575-2774-e2dc21fc891a"><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Chrome 86 introduces two new features that improve both the user and developer experience when it comes to working with focus.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">The </span><span style="font-family: courier; font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; font-weight: 700; vertical-align: baseline; white-space: pre-wrap;">:focus-visible</span><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"> pseudo-class is a CSS selector that lets developers opt-in to the same heuristic the browser uses when it's deciding whether to show a default focus indicator.

This is sometimes referred to as the "focus ring" because browsers typically put a solid or dashed ring around the focused element.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt; text-align: center;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><span style="border: none; display: inline-block; height: 251px; overflow: hidden; width: 436px;"><img alt="A button with a default blue focus ring" height="251" src="https://lh3.googleusercontent.com/NbcOQJzyX1gevtpZwLJe7AOzX4ASBEgdbSQGAcIHrO7GwPN_Hv5jvMjeT62VPXjUZuE24BEJXL2khAKa3gOMCea7fZL-rrZUl1uDEkygXusj3As5LjkVpfOoBDFQ-SggZ6l7kUTLtA" style="margin-left: 0px; margin-top: 0px;" width="436" /></span></span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">The focus ring signals to the user which element will receive keyboard events. If a user is tabbing through a form, the focus ring indicates which text field they can type into, or if they've focused a submit button they will know that pressing Enter or Spacebar will activate that button.</span></p><h2 dir="ltr" style="line-height: 1.38; margin-bottom: 6pt; margin-top: 18pt;"><span face="" style="font-size: 16pt; font-variant-east-asian: normal; font-variant-numeric: normal; font-weight: 400; vertical-align: baseline; white-space: pre-wrap;">Problems with focus</span></h2><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">For users who rely on a keyboard or other assistive technology to access the page, the focus ring acts as their mouse pointer - it's how they know what they are interacting with.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Unfortunately, many websites hide the focus ring using CSS. Oftentimes they do this because the underlying behavior of focus can be difficult to understand, and styling focus can have surprising consequences.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">For example, a custom dropdown menu should use the <span style="font-family: courier;">tabindex</span> attribute to make itself keyboard operable. But adding a <span style="font-family: courier;">tabindex</span> to an element causes all browsers to show a focus ring on that element if it is clicked with a mouse. If a developer is surprised to see the focus ring when they click the menu, they might use the following CSS to hide it:</span></p><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><br /></span></p> <pre class="code-block">.custom-dropdown-menu:focus { outline: none; }</pre> <br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">This "fixes" their issue, insofar as they no longer see the focus ring when they click the menu. However, they have unknowingly broken the experience for users relying on a keyboard to access the page. As mentioned earlier, for users who rely on a keyboard to access the page, the focus ring acts as their mouse pointer. Therefore, CSS that removes the focus ring (without providing an alternative) is akin to hiding the mouse pointer.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">To improve on this situation, developers need a better way to style focus - one that matches their expectations of how focus should work, and doesn't run the risk of breaking the experience for users. At the same time, users need to have the final say in the experience and should be able to choose when and how they see focus. This is where <span style="font-family: courier;">:focus-visible</span> and the Quick Focus Highlight come in.</span></p><h2 dir="ltr" style="line-height: 1.38; margin-bottom: 6pt; margin-top: 18pt;"><span style="font-family: courier; font-size: 16pt; font-variant-east-asian: normal; font-variant-numeric: normal; font-weight: 400; vertical-align: baseline; white-space: pre-wrap;">:focus-visible</span></h2><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Whenever you click on an element, browsers use an internal heuristic to determine whether they should display a default focus indicator. This is why in Chrome tabbing to a <span style="font-family: courier;"><button></span> shows a focus ring, but clicking it with a mouse does not. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">When you use <span style="font-family: courier;">:focus</span> to style an element, it tells the browser to ignore its heuristic and to always show your focus style. For some situations this can break the user's expectation and lead to a confusing experience.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><span style="font-family: courier;">:focus-visible</span>, on the other hand, will invoke the same heuristic that the browser uses when it's deciding whether to show the default focus indicator. This allows focus styles to feel more intuitive. In Chrome 86 and beyond, this should be all you need to style focus:</span></p><br /> <pre class="code-block">/* Focusing the button with a keyboard will show a dashed black line. */ button:focus-visible { outline: 4px dashed black; }</pre> <br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">By combining <span style="font-family: courier;">:focus-visible</span> with <span style="font-family: courier;">:focus</span> you can take things a step further and provide different focus styles depending on the user's input device. This can be helpful if you want the focus indicator to depend  on the precision of the input device:</span></p><br /> <pre class="code-block">/* Focusing the button with a keyboard will show a dashed black line. */ button:focus-visible { outline: 4px dashed black; } /* Focusing the button with a mouse, touch, or stylus will show a subtle drop shadow. */ button:focus:not(:focus-visible) { outline: none; box-shadow: 1px 1px 5px rgba(1, 1, 0, .7); }</pre> <iframe allowfullscreen="true" allowtransparency="true" frameborder="no" height="340" loading="lazy" scrolling="no" src="https://codepen.io/robdodson/embed/gOrLjvX?height=265&theme-id=dark&default-tab=result" style="width: 100%;" title=":focus-visible example"> See the Pen <a href='https://codepen.io/robdodson/pen/gOrLjvX'>:focus-visible example</a> by Rob Dodson (<a href='https://codepen.io/robdodson'>@robdodson</a>) on <a href='https://codepen.io'>CodePen</a>. </iframe> <br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">The snippet above says that if the browser would normally show a focus indicator, then it should do so using a 4px dashed black outline. Additionally, the example relies on the existing <span style="font-family: courier;">:focus</span> behavior and says that if an element has focus, but the browser would not normally show a default focus ring, then it should show a drop shadow. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Since the browser doesn't usually show a default focus ring when a user clicks on  a button, the <span style="font-family: courier;">:focus:not(:focus-visible)</span> pattern can be an easy way to specifically target mouse/touch focus.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Note that not all browsers set focus in the same way, so the above snippet will work in Chromium based browsers, but may not work in others.</span></p><h3 dir="ltr" style="line-height: 1.38; margin-bottom: 4pt; margin-top: 16pt;"><span face="" style="color: #434343; font-size: 14pt; font-variant-east-asian: normal; font-variant-numeric: normal; font-weight: 400; vertical-align: baseline; white-space: pre-wrap;">The <span style="font-family: courier;">:focus-visible</span> heuristic</span></h3><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Understanding the browsers’ heuristics for focus indicators will help you understand when to use <span style="font-family: courier;">:focus-visible</span>.

Oftentimes they do this because the underlying behavior of focus can be difficult to understand, and styling focus can have surprising consequences.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">For example, a custom dropdown menu should use the <span style="font-family: courier;">tabindex</span> attribute to make itself keyboard operable. But adding a <span style="font-family: courier;">tabindex</span> to an element causes all browsers to show a focus ring on that element if it is clicked with a mouse. If a developer is surprised to see the focus ring when they click the menu, they might use the following CSS to hide it:</span></p><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><br /></span></p> <pre class="code-block">.custom-dropdown-menu:focus { outline: none; }</pre> <br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">This "fixes" their issue, insofar as they no longer see the focus ring when they click the menu. However, they have unknowingly broken the experience for users relying on a keyboard to access the page. As mentioned earlier, for users who rely on a keyboard to access the page, the focus ring acts as their mouse pointer. Therefore, CSS that removes the focus ring (without providing an alternative) is akin to hiding the mouse pointer.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">To improve on this situation, developers need a better way to style focus - one that matches their expectations of how focus should work, and doesn't run the risk of breaking the experience for users. At the same time, users need to have the final say in the experience and should be able to choose when and how they see focus. This is where <span style="font-family: courier;">:focus-visible</span> and the Quick Focus Highlight come in.</span></p><h2 dir="ltr" style="line-height: 1.38; margin-bottom: 6pt; margin-top: 18pt;"><span style="font-family: courier; font-size: 16pt; font-variant-east-asian: normal; font-variant-numeric: normal; font-weight: 400; vertical-align: baseline; white-space: pre-wrap;">:focus-visible</span></h2><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">Whenever you click on an element, browsers use an internal heuristic to determine whether they should display a default focus indicator. This is why in Chrome tabbing to a <span style="font-family: courier;"><button></span> shows a focus ring, but clicking it with a mouse does not. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">When you use <span style="font-family: courier;">:focus</span> to style an element, it tells the browser to ignore its heuristic and to always show your focus style. For some situations this can break the user's expectation and lead to a confusing experience.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><span style="font-family: courier;">:focus-visible</span>, on the other hand, will invoke the same heuristic that the browser uses when it's deciding whether to show the default focus indicator. This allows focus styles to feel more intuitive. In Chrome 86 and beyond, this should be all you need to style focus:</span></p><br /> <pre class="code-block">/* Focusing the button with a keyboard will show a dashed black line. */ button:focus-visible { outline: 4px dashed black; }</pre> <br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">By combining <span style="font-family: courier;">:focus-visible</span> with <span style="font-family: courier;">:focus</span> you can take things a step further and provide different focus styles depending on the user's input device. This can be helpful if you want the focus indicator to depend  on the precision of the input device:</span></p><br /> <pre class="code-block">/* Focusing the button with a keyboard will show a dashed black line. */ button:focus-visible { outline: 4px dashed black; } /* Focusing the button with a mouse, touch, or stylus will show a subtle drop shadow. */ button:focus:not(:focus-visible) { outline: none; box-shadow: 1px 1px 5px rgba(1, 1, 0, .7); }</pre> <iframe allowfullscreen="true" allowtransparency="true" frameborder="no" height="340" loading="lazy" scrolling="no" src="https://codepen.io/robdodson/embed/gOrLjvX?height=265&theme-id=dark&default-tab=result" style="width: 100%;" title=":focus-visible example"> See the Pen <a href='https://codepen.io/robdodson/pen/gOrLjvX'>:focus-visible example</a> by Rob Dodson (<a href='https://codepen.io/robdodson'>@robdodson</a>) on <a href='https://codepen.io'>CodePen</a>. </iframe> <br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span face="" style="font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;">The snippet above says that if the browser would normally show a focus indicator, then it should do so using a 4px dashed black outline.
