href="/en-US/docs/Web/Accessibility/ARIA/Roles/checkbox_role">checkbox</a> role, except instead of being "checked" or "unchecked", it is either "on" or "off". Like the <a href="/en-US/docs/Web/Accessibility/ARIA/Roles/checkbox_role">checkbox</a> role, the <a href="/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-checked"><code>aria-checked</code></a> attribute is required. The two possible values are <code>true</code> and <code>false</code>. Unlike an <code><input type="checkbox"></code> or <code>role="checkbox"</code>, there is no <code>indeterminate</code> or <code>mixed</code> state. The <code>switch</code> role does not support the value <code>mixed</code> for the <code>aria-checked</code> attribute; assigning a value of <code>mixed</code> to a <code>switch</code> instead sets the value to <code>false</code>.</p> <p>Assistive technologies may choose to represent <code>switch</code> widgets with a specialized presentation to reflect the notion of an on/off switch.</p> <p>Since a switch is an interactive control, it must be focusable and keyboard accessible. If the role is applied to a non-focusable element, use the <code>tabindex</code> attribute to change this. The expected keyboard shortcut for toggling the value of a switch is the <kbd>Space</kbd> key. The developer is required to change the value of the <code>aria-checked</code> attribute dynamically when the switch is toggled.</p></div></section><section aria-labelledby="all_descendants_are_presentational"><h3 id="all_descendants_are_presentational"><a href="#all_descendants_are_presentational">All descendants are presentational</a></h3><div class="section-content"><p>There are some types of user interface components that, when represented in a platform accessibility API, can only contain text.

The button is styled with an appearance reminiscent of an on/off power switch.</p> <h4 id="html">HTML</h4> <p>The HTML is fairly simple here. The switch is implemented as a <a href="/en-US/docs/Web/HTML/Element/button"><code><button></code></a> element which is initially checked courtesy of its <code>aria-checked</code> attribute being set to <code>"true"</code>. The switch has two child elements containing the "off" and "on" labels and is followed by a <a href="/en-US/docs/Web/HTML/Element/label"><code><label></code></a> identifying the switch.</p> <div class="code-example"><div class="example-header"><span class="language-name">html</span></div><pre class="brush: html notranslate"><code><button role="switch" aria-checked="true" id="speakerPower" class="switch"> <span>off</span> <span>on</span> </button> <label for="speakerPower" class="switch">Speaker power</label> </code></pre></div> <h4 id="javascript">JavaScript</h4> <p>This JavaScript code defines and applies a function to handle click events on switch widgets. The function changes the <code>aria-checked</code> attribute from <code>true</code> to <code>false</code>, or vice versa.</p> <div class="code-example"><div class="example-header"><span class="language-name">js</span></div><pre class="brush: js notranslate"><code>document.querySelectorAll(".switch").forEach((theSwitch) => { theSwitch.addEventListener("click", handleClickEvent, false); }); function handleClickEvent(evt) { const el = evt.target; if (el.getAttribute("aria-checked") === "true") { el.setAttribute("aria-checked", "false"); } else { el.setAttribute("aria-checked", "true"); } } </code></pre></div> <h4 id="css">CSS</h4> <p>The purpose of the CSS is to establish a look and feel for the switch that's reminiscent of the power switch paradigm.</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css notranslate"><code>button.switch { margin: 0; padding: 0; width: 70px; height: 26px; border: 2px solid black; display: inline-block; margin-right: 0.25em; line-height: 20px; vertical-align: middle; text-align: center; font: 12px "Open Sans", "Arial", serif; } button.switch span {

vertical-align: middle; user-select: none; } </code></pre></div> <p>The most interesting part is probably the use of attribute selectors and the <a href="/en-US/docs/Web/CSS/:first-child"><code>:first-child</code></a> and <a href="/en-US/docs/Web/CSS/:last-child"><code>:last-child</code></a> pseudo-classes to do all the heavy lifting of changing the appearance of the switch based on whether it's on or off.</p> <h4 id="result">Result</h4> <p>The result looks like this:</p><div class="code-example"><div class="example-header"></div><iframe
