HTML attribute
open-in-new
<h2 id="description">Description</h2> <p>HTML attributes generally appear as <a href="/facts/Name%25E2%2580%2593value_pair/buweLY96">name–value pairs</a>, separated by =, and are written within the start tag of an element, after the element's name: </p> <element attribute="value">element content</element> <p>Where element names the HTML element type, and attribute is the name of the attribute, set to the provided value. The value may be enclosed in single or double quotes, although values consisting of certain characters can be left unquoted in HTML (but not XHTML).<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a><a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> Leaving attribute values unquoted is considered unsafe.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p><p>Although most attributes are provided as paired names and values, some affect the element simply by their presence in the start tag of the element<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> (like the ismap attribute for the img element<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a>). </p><p>The abbreviation element, abbr, can be used to demonstrate these various attributes: </p> <abbr id="anId" class="aClass" style="color:blue;" title="Hypertext Markup Language">HTML</abbr> <p>This example displays as HTML in blue without being a link, and in most browsers, pointing the cursor at the abbreviation should display the title text "Hypertext Markup Language" within a floating yellow background (<a href="/facts/Tooltip/alzUJ5c2">tooltip</a>). </p> <div style="text-align: center;">Centered text</div> <p>In this other example, your text will look like this: </p> Centered text <p>Most elements also take the language-related attributes lang and dir. </p> <h3>Common attributes</h3> <p>Usually, <a href="/facts/HTML_element/s4TKzjUP">HTML elements</a> can take any of several most common standard attributes (See the complete list): </p> <ul><li>The id attribute provides a document-wide unique identifier for an element.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a><a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a><a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> This can be used as <a href="/facts/CSS_selector/tA90XBQo">CSS selector</a> to provide presentational properties, by browsers to focus attention on the specific element, or by scripts to alter the contents or presentation of an element. Appended to the URL of the page, the URL directly targets the specific element within the document, typically a sub-section of the page. For example, the ID "Attributes" in http://en.wikipedia.org/wiki/HTML#Attributes (to refer to the section "Attributes" in the "HTML" page).</li> <li>The class attribute provides a way of classifying similar elements. Multiple class names can be added by separating them with spaces.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a><a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> Semantically, for example, classes are used in <a href="/facts/Microformat/NCueM8H6">microformats</a>. Additionally authors of style sheets can construct <a href="/facts/CSS_selector/tA90XBQo">selectors</a> that match elements by class for styling purposes. For example, a HTML document might use the designation class="notation" to indicate that all elements with this class value are subordinate to the main text of the document. Such elements might be gathered together as footnotes on a page—instead of appearing in the place suggested by their position within the HTML source. The style sheet author might also define a rule with the .notation selector and define the property font-size: small;.</li> <li>The style attribute provides a way of applying element-specific style rules. Multiple <a href="/facts/CSS/tA90XBQo">style declarations</a> can be added by separating them with semicolons and an optional space, where each declaration includes a CSS property name and a value separated by a colon and an optional space (Example: style="color: red; text-align: center;").<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a><a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a><a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> The style attribute can be used on any HTML element (it will validate on any HTML element; however, it is not necessarily useful). It is considered better practice to add the style information to a <a href="/facts/Style_sheet_(web_development)/6vHquHxG">style sheet</a>, often accomplished with selectors that match the element class or ID. Sometimes, however, inline styles are favored where style sheets are considered too cumbersome for a simple and specific or ad hoc style specification.</li> <li>The title attribute is used to attach subtextual explanation to an element. In most browsers this attribute is displayed as what is often referred to as a <a href="/facts/Tooltip/alzUJ5c2">tooltip</a>.</li></ul> <h2 id="varieties">Varieties</h2> <p>HTML attributes are generally classified as required attributes, optional attributes, standard attributes, and event attributes: </p> <ul><li>Usually the required and optional attributes modify specific HTML elements</li> <li>While the standard attributes can be applied to most HTML elements.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a></li> <li>Event attributes, added in HTML version 4, allow an element to specify <a href="/facts/JavaScript/XhhIIEsl">scripts</a> to be run under specific circumstances.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a></li></ul> <h2 id="required-and-optional">Required and optional</h2> <h3>Used by two elements</h3> <ul><li><a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a"><a></a> and <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/area"><area></a>: <ul><li>coords — coordinates of an <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/area#attr-coords"><area></a> or a <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/link#attr-coords"><link></a> within it.</li> <li>shape — shape of an <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/area#attr-shape"><area></a> or a <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/link#attr-shape"><link></a> within it.
