Many of the text elements are mentioned in the 1988 ISO technical report TR 9537 <i>Techniques for using SGML</i>, which describes the features of early text formatting languages such as that used by the <a href="/wiki/TYPSET_and_RUNOFF" title="TYPSET and RUNOFF">RUNOFF command</a> developed in the early 1960s for the <a href="/wiki/Compatible_Time-Sharing_System" title="Compatible Time-Sharing System">CTSS</a> (Compatible Time-Sharing System) operating system. These formatting commands were derived from the commands used by typesetters to manually format documents. However, the SGML concept of generalized markup is based on elements (nested annotated ranges with attributes) rather than merely print effects, with separate structure and markup. HTML has been progressively moved in this direction with CSS. </p><p>Berners-Lee considered HTML to be an application of SGML.

Structural markup does not denote any specific rendering, but most web browsers have default styles for element formatting. Content may be further styled using <a href="/wiki/Cascading_Style_Sheets" class="mw-redirect" title="Cascading Style Sheets">Cascading Style Sheets</a> (CSS).<sup id="cite_ref-73" class="reference"><a href="#cite_note-73"><span class="cite-bracket">[</span>73<span class="cite-bracket">]</span></a></sup></dd> <dt>Presentational markup indicates the appearance of the text, regardless of its purpose</dt> <dd>For example, <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">b</span><span class="p">></span>bold text<span class="p"></</span><span class="nt">b</span><span class="p">></span></code> indicates that visual output devices should render "boldface" in bold text, but gives a little indication what devices that are unable to do this (such as aural devices that read the text aloud) should do.

It is easier to see how an aural user agent should interpret the latter two elements. However, they are not equivalent to their presentational counterparts: it would be undesirable for a screen reader to emphasize the name of a book, for instance, but on a screen, such a name would be italicized.

This is used to identify the element so that stylesheets can alter its presentational properties, and scripts may alter, animate or delete its contents or presentation. Appended to the URL of the page, it provides a globally unique identifier for the element, typically a sub-section of the page. For example, the ID "Attributes" in <code>https://en.wikipedia.org/wiki/HTML#Attributes</code>.</li> <li>The <code>class</code> attribute provides a way of classifying similar elements. This can be used for <a href="/wiki/Semantics" title="Semantics">semantic</a> or presentation purposes. For example, an HTML document might semantically use the designation <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">class</span><span class="err">="</span><span class="na">notation</span><span class="err">"</span><span class="p">></span></code> to indicate that all elements with this class value are subordinate to the main text of the document. In presentation, such elements might be gathered together and presented as footnotes on a page instead of appearing in the place where they occur in the HTML source. Class attributes are used semantically in <a href="/wiki/Microformat" title="Microformat">microformats</a>. Multiple class values may be specified; for example <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">class</span><span class="err">="</span><span class="na">notation</span> <span class="na">important</span><span class="err">"</span><span class="p">></span></code> puts the element into both the <code>notation</code> and the <code>important</code> classes.</li> <li>An author may use the <code>style</code> attribute to assign presentational properties to a particular element. It is considered better practice to use an element's <code>id</code> or <code>class</code> attributes to select the element from within a <a href="/wiki/Cascading_Style_Sheets" class="mw-redirect" title="Cascading Style Sheets">stylesheet</a>, though sometimes this can be too cumbersome for a simple, specific, or ad hoc styling.</li> <li>The <code>title</code> attribute is used to attach a subtextual explanation to an element. In most <a href="/wiki/Web_browser" title="Web browser">browsers</a> this attribute is displayed as a <a href="/wiki/Tooltip" title="Tooltip">tooltip</a>.</li> <li>The <code>lang</code> attribute identifies the natural language of the element's contents, which may be different from that of the rest of the document. For example, in an English-language document: <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><span></span><span class="p"><</span><span class="nt">p</span><span class="p">></span>Oh well, <span class="p"><</span><span class="nt">span</span> <span class="na">lang</span><span class="o">=</span><span class="s">"fr"</span><span class="p">></span>c'est la vie<span class="p"></</span><span class="nt">span</span><span class="p">></span>, as they say in France.<span class="p"></</span><span class="nt">p</span><span class="p">></span> </pre></div></li></ul> <p>The abbreviation element, <code>abbr</code>, can be used to demonstrate some of these attributes: </p> <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><span></span><span class="p"><</span><span class="nt">abbr</span> <span class="na">id</span><span class="o">=</span><span class="s">"anId"</span> <span class="na">class</span><span class="o">=</span><span class="s">"jargon"</span> <span class="na">style</span><span class="o">=</span><span class="s">"color:purple;"</span> <span class="na">title</span><span class="o">=</span><span class="s">"Hypertext Markup Language"</span><span class="p">></span>HTML<span class="p"></</span><span class="nt">abbr</span><span class="p">></span> </pre></div> <p>This example displays as <abbr id="anId" class="jargon" style="color:purple;" title="Hypertext Markup Language">HTML</abbr>; in most browsers, pointing the cursor at the abbreviation should display the title text "Hypertext Markup Language." </p><p>Most elements take the language-related attribute <code>dir</code> to specify text direction, such as with "rtl" for right-to-left text in, for example, <a href="/wiki/Arabic_language" class="mw-redirect" title="Arabic language">Arabic</a>, <a href="/wiki/Persian_language" title="Persian language">Persian</a> or <a href="/wiki/Hebrew_language" title="Hebrew language">Hebrew</a>.<sup id="cite_ref-78" class="reference"><a href="#cite_note-78"><span class="cite-bracket">[</span>78<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Character_and_entity_references">Character and entity references</h3></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/List_of_XML_and_HTML_character_entity_references" title="List of XML and HTML character entity references">List of XML and HTML character entity references</a> and <a href="/wiki/Unicode_and_HTML" title="Unicode and HTML">Unicode and HTML</a></div> <p>As of version 4.0, HTML defines a set of 252 <a href="/wiki/Character_entity_reference" class="mw-redirect" title="Character entity reference">character entity references</a> and a set of 1,114,050 <a href="/wiki/Numeric_character_reference" title="Numeric character reference">numeric character references</a>, both of which allow individual characters to be written via simple markup, rather than literally. A literal character and its markup counterpart are considered equivalent and are rendered identically. </p><p>The ability to "<a href="/wiki/Escape_character" title="Escape character">escape</a>" characters in this way allows for the characters <code><</code> and <code>&</code> (when written as <code>&lt;</code> and <code>&amp;</code>, respectively) to be interpreted as character data, rather than markup. For example, a literal <code><</code> normally indicates the start of a tag, and <code>&</code> normally indicates the start of a character entity reference or numeric character reference; writing it as <code>&amp;</code> or <code>&#x26;</code> or <code>&#38;</code> allows <code>&</code> to be included in the content of an element or in the value of an attribute. The double-quote character (<code>"</code>), when not used to quote an attribute value, must also be escaped as <code>&quot;</code> or <code>&#x22;</code> or <code>&#34;</code> when it appears within the attribute value itself. Equivalently, the single-quote character (<code>'</code>), when not used to quote an attribute value, must also be escaped as <code>&#x27;</code> or <code>&#39;</code> (or as <code>&apos;</code> in HTML5 or XHTML documents<sup id="cite_ref-79" class="reference"><a href="#cite_note-79"><span class="cite-bracket">[</span>79<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-aposhtml_80-0" class="reference"><a href="#cite_note-aposhtml-80"><span class="cite-bracket">[</span>80<span class="cite-bracket">]</span></a></sup>) when it appears within the attribute value itself. If document authors overlook the need to escape such characters, some browsers can be very forgiving and try to use context to guess their intent. The result is still invalid markup, which makes the document less accessible to other browsers and to other <a href="/wiki/User_agent" title="User agent">user agents</a> that may try to parse the document for <a href="/wiki/Web_crawler" title="Web crawler">search and indexing</a> purposes for example. </p><p>Escaping also allows for characters that are not easily typed, or that are not available in the document's <a href="/wiki/Character_encoding" title="Character encoding">character encoding</a>, to be represented within the element and attribute content. For example, the acute-accented <code>e</code> (<code>é</code>), a character typically found only on Western European and South American keyboards, can be written in any HTML document as the entity reference <code>&eacute;</code> or as the numeric references <code>&#xE9;</code> or <code>&#233;</code>, using characters that are available on all keyboards and are supported in all character encodings. <a href="/wiki/Unicode" title="Unicode">Unicode</a> character encodings such as <a href="/wiki/UTF-8" title="UTF-8">UTF-8</a> are compatible with all modern browsers and allow direct access

However, no clear standards existed in the early years of the language. Though its creators originally conceived of HTML as a semantic language devoid of presentation details,<sup id="cite_ref-93" class="reference"><a href="#cite_note-93"><span class="cite-bracket">[</span>93<span class="cite-bracket">]</span></a></sup> practical uses pushed many presentational elements and attributes into the language, driven largely by the various browser vendors. The latest standards surrounding HTML reflect efforts to overcome the sometimes chaotic development of the language<sup id="cite_ref-94" class="reference"><a href="#cite_note-94"><span class="cite-bracket">[</span>94<span class="cite-bracket">]</span></a></sup> and to create a rational foundation for building both meaningful and well-presented documents. To return HTML to its role as a semantic language, the <a href="/wiki/World_Wide_Web_Consortium" title="World Wide Web Consortium">W3C</a> has developed style languages such as <a href="/wiki/Cascading_Style_Sheets" class="mw-redirect" title="Cascading Style Sheets">CSS</a> and <a href="/wiki/XSL" title="XSL">XSL</a> to shoulder the burden of presentation. In conjunction, the HTML specification has slowly reined in the presentational elements. </p><p>There are two axes differentiating various variations of HTML as currently specified: SGML-based HTML versus XML-based HTML (referred to as XHTML) on one axis, and strict versus transitional (loose) versus frameset on the other axis. </p> <div class="mw-heading mw-heading3"><h3 id="SGML-based_versus_XML-based_HTML">SGML-based versus XML-based HTML</h3></div> <p>One difference in the latest<sup class="noprint Inline-Template" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Manual_of_Style/Dates_and_numbers#Chronological_items" title="Wikipedia:Manual of Style/Dates and numbers"><span title="The time period mentioned near this tag is ambiguous. (March 2022)">when?</span></a></i>]</sup> HTML specifications lies in the distinction between the SGML-based specification and the XML-based specification. The XML-based specification is usually called <a href="/wiki/XHTML" title="XHTML">XHTML</a> to distinguish it clearly from the more traditional definition. However, the root element name continues to be "html" even in the XHTML-specified HTML. The W3C intended XHTML 1.0 to be identical to HTML 4.01 except where limitations of XML over the more complex SGML require workarounds. Because XHTML and HTML are closely related, they are sometimes documented in parallel. In such circumstances, some authors <a href="/wiki/(X)HTML" class="mw-redirect" title="(X)HTML">conflate the two names</a> as (X)HTML or X(HTML). </p><p>Like HTML 4.01, XHTML 1.0 has three sub-specifications: strict, transitional, and frameset. </p><p>Aside from the different opening declarations for a document, the differences between an HTML 4.01 and XHTML 1.0 document—in each of the corresponding DTDs—are largely syntactic. The underlying syntax of HTML allows many shortcuts that XHTML does not, such as elements with optional opening or closing tags, and even empty elements which must not have an end tag. By contrast, XHTML requires all elements to have an opening tag and a closing tag. XHTML, however, also introduces a new shortcut: an XHTML tag may be opened and closed within the same tag, by including a slash before the end of the tag like this: <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">br</span> <span class="p">/></span></code>. The introduction of this shorthand, which is not used in the SGML declaration for HTML 4.01, may confuse earlier software unfamiliar with this new convention. A fix for this is to include a space before closing the tag, as such: <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">br</span> <span class="p">/></span></code>.<sup id="cite_ref-95" class="reference"><a href="#cite_note-95"><span class="cite-bracket">[</span>95<span class="cite-bracket">]</span></a></sup> </p><p>To understand the subtle differences between HTML and XHTML, consider the transformation of a valid and well-formed XHTML 1.0 document that adheres to Appendix C (see below) into a valid HTML 4.01 document. Making this translation requires the following steps: </p> <ol><li><b>The language for an element should be specified with a <code>lang</code> attribute rather than the XHTML <code>xml:lang</code> attribute.</b> XHTML uses XML's built-in language-defining functionality attribute.</li> <li><b>Remove the XML namespace (<code>xmlns=URI</code>).</b> HTML has no facilities for namespaces.</li> <li><b>Change the document type declaration</b> from XHTML 1.0 to HTML 4.01. (see <a href="#Document_type_declaration">DTD section</a> for further explanation).</li> <li>If present, <b>remove the XML declaration.</b> (Typically this is: <code class="mw-highlight mw-highlight-lang-xml mw-content-ltr" style="" dir="ltr"><span class="cp"><?xml version="1.0" encoding="utf-8"?></span></code>).</li> <li><b>Ensure that the document's MIME type is set to <code>text/html</code>.</b> For both HTML and XHTML, this comes from the HTTP <code>Content-Type</code> header sent by the server.</li> <li><b>Change the XML empty-element syntax to an HTML style empty element</b> (<code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">br</span> <span class="p">/></span></code> to <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">br</span> <span class="p">/></span></code>).</li></ol> <p>Those are the main changes necessary to translate a document from XHTML 1.0 to HTML 4.01. To translate from HTML to XHTML would also require the addition of any omitted opening or closing tags. Whether coding in HTML or XHTML it may just be best to always include the optional tags within an HTML document rather than remembering which tags can be omitted. </p><p>A well-formed XHTML document adheres to all the syntax requirements of XML. A valid document adheres to the content specification for XHTML, which describes the document structure. </p><p>The W3C recommends several conventions to ensure an easy migration between HTML and XHTML (see <a rel="nofollow" class="external text" href="https://www.w3.org/TR/xhtml1/#guidelines">HTML Compatibility Guidelines</a>). The following steps can be applied to XHTML 1.0 documents only: </p> <ul><li>Include both <code>xml:lang</code> and <code>lang</code> attributes on any elements assigning language.</li> <li>Use the empty-element syntax only for elements specified as empty in HTML.</li> <li>Include an extra space in empty-element tags: for example <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">br</span> <span class="p">/></span></code> instead of <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">br</span> <span class="p">/></span></code>.</li> <li>Include explicit close tags for elements that permit content but are left empty (for example, <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"></code>, not <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><span class="p"><</span><span class="nt">div</span> <span class="p">/></span></code>).</li> <li>Omit the XML declaration.</li></ul> <p>By carefully following the W3C's compatibility guidelines, a user agent should be able to interpret the document equally as HTML or XHTML. For documents that are XHTML 1.0 and have been made compatible in this way, the W3C permits them to be served either as HTML (with a <code>text/html</code> <a href="/wiki/MIME_type" class="mw-redirect" title="MIME type">MIME type</a>), or as XHTML (with an <code>application/xhtml+xml</code> or <code>application/xml</code> MIME type). When delivered as XHTML, browsers should use an XML parser, which adheres strictly to the XML specifications for parsing the document's contents. </p> <div class="mw-heading mw-heading3"><h3 id="Transitional_versus_strict">Transitional versus strict</h3></div> <p>HTML 4 defined three different versions of the language: Strict, Transitional (once called Loose), and Frameset. The Strict version is intended for new documents and is considered best practice, while the Transitional and Frameset versions were developed to make it easier to transition documents that conformed to older HTML specifications or did not conform to any specification to a version of HTML 4. The Transitional and Frameset versions allow for presentational markup, which is omitted in the Strict version. Instead, <a href="/wiki/Cascading_style_sheets" class="mw-redirect" title="Cascading style sheets">cascading style sheets</a> are encouraged to improve the presentation of HTML documents. Because XHTML 1 only defines an XML syntax for the language defined by HTML 4, the same differences apply to XHTML 1 as well. </p><p>The Transitional version allows the following parts of the vocabulary, which are not included in the Strict version: </p> <ul><li><b>A looser content model</b> <ul><li>Inline elements and plain text are allowed directly in: <code>body</code>, <code>blockquote</code>, <code>form</code>, <code>noscript</code> and <code>noframes</code></li></ul></li> <li><b>Presentation related elements</b> <ul><li>underline (<code>u</code>)(Deprecated. can confuse a visitor with a hyperlink.)</li> <li>strike-through (<code>s</code>)</li> <li><code>center</code> (Deprecated. use CSS instead.)</li> <li><code>font</code> (Deprecated. use CSS instead.)</li> <li><code>basefont</code> (Deprecated. use CSS instead.)</li></ul></li> <li><b>Presentation related attributes</b> <ul><li><code>background</code> (Deprecated. use CSS instead.) and <code>bgcolor</code> (Deprecated. use CSS instead.) attributes for <code>body</code> (required element according to the W3C.) element.</li> <li><code>align</code> (Deprecated. use CSS instead.) attribute on <code>div</code>, <code>form</code>, paragraph (<code>p</code>) and heading (<code>h1</code>...<code>h6</code>) elements</li> <li><code>align</code> (Deprecated. use CSS instead.), <code>noshade</code> (Deprecated. use CSS instead.), <code>size</code> (Deprecated. use CSS instead.) and <code>width</code> (Deprecated. use CSS instead.) attributes on <code>hr</code> element</li> <li><code>align</code> (Deprecated. use CSS instead.), <code>border</code>, <code>vspace</code> and <code>hspace</code> attributes on <code>img</code> and <code>object</code> (caution: the <code>object</code> element is only supported in Internet Explorer (from the major browsers)) elements</li> <li><code>align</code> (Deprecated. use CSS instead.) attribute on <code>legend</code> and <code>caption</code> elements</li> <li><code>align</code> (Deprecated. use CSS instead.) and <code>bgcolor</code> (Deprecated. use CSS instead.) on <code>table</code> element</li> <li><code>nowrap</code> (Obsolete), <code>bgcolor</code> (Deprecated. use CSS instead.), <code>width</code>, <code>height</code> on <code>td</code> and <code>th</code> elements</li> <li><code>bgcolor</code> (Deprecated. use CSS instead.) attribute on <code>tr</code> element</li> <li><code>clear</code> (Obsolete) attribute on <code>br</code> element</li> <li><code>compact</code> attribute on <code>dl</code>, <code>dir</code> and <code>menu</code> elements</li> <li><code>type</code> (Deprecated. use CSS instead.), <code>compact</code> (Deprecated. use CSS instead.) and <code>start</code> (Deprecated. use CSS instead.) attributes on <code>ol</code> and <code>ul</code> elements</li> <li><code>type</code> and <code>value</code> attributes on <code>li</code> element</li> <li><code>width</code> attribute on <code>pre</code> element</li></ul></li> <li><b>Additional elements in Transitional specification</b> <ul><li><code>menu</code> (Deprecated. use CSS instead.) list (no substitute, though the unordered list, is recommended)</li> <li><code>dir</code> (Deprecated. use CSS instead.) list (no substitute, though the unordered list is recommended)</li> <li><code>isindex</code> (Deprecated.)

However, contrary to popular misconceptions, the move to XHTML does not imply a removal of this legacy support. Rather the X in XML stands for extensible and the W3C is modularizing the entire specification and opens it up to independent extensions. The primary achievement in the move from XHTML 1.0 to XHTML 1.1 is the modularization of the entire specification. The strict version of HTML is deployed in XHTML 1.1 through a set of modular extensions to the base XHTML 1.1 specification. Likewise, someone looking for the loose (transitional) or frameset specifications will find similar extended XHTML 1.1 support (much of it is contained in the legacy or frame modules). Modularization also allows for separate features to develop on their own timetable. So for example, XHTML 1.1 will allow quicker migration to emerging XML standards such as <a href="/wiki/MathML" title="MathML">MathML</a> (a presentational and semantic math language based on XML) and <a href="/wiki/XForms" title="XForms">XForms</a>—a new highly advanced web-form technology to replace the existing HTML forms. </p><p>In summary, the HTML 4 specification primarily reined in all the various HTML implementations into a single clearly written specification based on SGML. XHTML 1.0, ported this specification, as is, to the new XML-defined specification. Next, XHTML 1.1 takes advantage of the extensible nature of XML and modularizes the whole specification. XHTML 2.0 was intended to be the first step in adding new features to the specification in a standards-body-based approach. </p> <div class="mw-heading mw-heading2"><h2 id="WHATWG_HTML_versus_HTML5">WHATWG HTML versus HTML5</h2></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="#Transition_of_HTML_Publication_to_WHATWG">§ Transition of HTML Publication to WHATWG</a></div> <p>The HTML Living Standard, which is developed by WHATWG, is the official version, while W3C HTML5 is no longer separate from WHATWG. </p> <div class="mw-heading mw-heading2"><h2 id="WYSIWYG_editors">WYSIWYG editors</h2></div> <style data-mw-deduplicate="TemplateStyles:r1251242444">.mw-parser-output .ambox{border:1px solid #a2a9b1;border-left:10px solid #36c;background-color:#fbfbfb;box-sizing:border-box}.mw-parser-output .ambox+link+.ambox,.mw-parser-output .ambox+link+style+.ambox,.mw-parser-output .ambox+link+link+.ambox,.mw-parser-output .ambox+.mw-empty-elt+link+.ambox,.mw-parser-output .ambox+.mw-empty-elt+link+style+.ambox,.mw-parser-output .ambox+.mw-empty-elt+link+link+.ambox{margin-top:-1px}html body.mediawiki .mw-parser-output .ambox.mbox-small-left{margin:4px 1em 4px 0;overflow:hidden;width:238px;border-collapse:collapse;font-size:88%;line-height:1.25em}.mw-parser-output .ambox-speedy{border-left:10px solid #b32424;background-color:#fee7e6}.mw-parser-output .ambox-delete{border-left:10px solid #b32424}.mw-parser-output .ambox-content{border-left:10px solid #f28500}.mw-parser-output .ambox-style{border-left:10px solid #fc3}.mw-parser-output .ambox-move{border-left:10px solid #9932cc}.mw-parser-output .ambox-protection{border-left:10px solid #a2a9b1}.mw-parser-output .ambox .mbox-text{border:none;padding:0.25em 0.5em;width:100%}.mw-parser-output .ambox .mbox-image{border:none;padding:2px 0 2px 0.5em;text-align:center}.mw-parser-output .ambox .mbox-imageright{border:none;padding:2px 0.5em 2px 0;text-align:center}.mw-parser-output .ambox .mbox-empty-cell{border:none;padding:0;width:1px}.mw-parser-output .ambox .mbox-image-div{width:52px}@media(min-width:720px){.mw-parser-output .ambox{margin:0 10%}}@media print{body.ns-0 .mw-parser-output .ambox{display:none!important}}</style><table class="box-Missing_information plainlinks metadata ambox ambox-content" role="presentation"><tbody><tr><td class="mbox-image"><div class="mbox-image-div"><span typeof="mw:File"><a href="/wiki/File:Wiki_letter_w.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/en/thumb/6/6c/Wiki_letter_w.svg/44px-Wiki_letter_w.svg.png" decoding="async" width="44" height="44" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/en/thumb/6/6c/Wiki_letter_w.svg/66px-Wiki_letter_w.svg.png 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/6/6c/Wiki_letter_w.svg/88px-Wiki_letter_w.svg.png 2x" data-file-width="44" data-file-height="44" /></a></span></div></td><td class="mbox-text"><div class="mbox-text-span">This article <b>is missing information</b> about contenteditable.<span class="hide-when-compact"> Please expand the article <span class="anonymous-show"><span class="plainlinks"><a class="external text" href="https://en.wikipedia.org/w/index.php?title=Talk%3AHTML&preload=Template%3ASubmit+an+edit+request%2Fpreload&action=edit&section=new&editintro=Template%3AEdit+protected%2Feditintro&preloadtitle=Protected+edit+request+on+23+November+2024&preloadparams%5B%5D=edit+fully-protected&preloadparams%5B%5D=HTML">by making an edit request</a></span></span><span class="user-show">to include this information </span>.
