others).[<a href="/wiki/Wikipedia:Vagueness" title="Wikipedia:Vagueness">vague</a>] The first used version of HTML was written by <a href="/wiki/Tim_Berners-Lee" title="Tim Berners-Lee">Tim Berners-Lee</a> in 1993 and there have since been many versions of HTML. The current de facto standard is governed by the industry group <a href="/wiki/WHATWG" title="WHATWG">WHATWG</a> and is known as the HTML Living Standard. An HTML document is composed of a <a href="/wiki/Tree_structure" title="Tree structure">tree</a> of simple HTML <a href="/wiki/Node_(computer_science)" title="Node (computer science)">nodes</a>, such as text nodes, and HTML elements, which add <a href="/wiki/Semantics" title="Semantics">semantics</a> and formatting to parts of a document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed <a href="/wiki/Hyperlink" title="Hyperlink">hyperlinks</a> and images).

For example, an HTML document always has a root <kbd><html></kbd> element, even if the string <kbd><html></kbd> doesn't appear anywhere in the markup. <div class="templatequotecite">— <cite><a rel="nofollow" class="external text" href="https://www.w3.org/TR/html51/syntax.html#optional-tags">HTML 5.1 2nd Edition § 8.1.2.4. Optional tags</a></cite></div></blockquote> As HTML (before HTML5) is based on <a href="/wiki/SGML" class="mw-redirect" title="SGML">SGML</a>,<a href="#cite_note-2">[2]</a> its parsing also depends on the <a href="/wiki/Document_Type_Definition" class="mw-redirect" title="Document Type Definition">Document Type Definition (DTD)</a>, specifically an HTML DTD (e.g. HTML 4.01<a href="#cite_note-W3C,_HTML_401_DTD-3">[3]</a><a href="#cite_note-4">[note 1]</a>). The DTD specifies which element types are possible (i.e. it defines the set of element types) and also the valid combinations in which they may appear in a document. It is part of general SGML behavior that, where only one valid structure is possible (per the DTD), its explicit statement in any given document is not generally required. As a simple example, the <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><p></code> tag indicating the start of a paragraph element should be complemented by a <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"></p></code> tag indicating its end. But since the DTD states that paragraph elements cannot be nested, an HTML document fragment <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><p>Para 1 <p>Para 2 <p>Para 3</code> is thus inferred to be equivalent to <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><p>Para 1 </p><p>Para 2 </p><p>Para 3</code>. (If one paragraph element cannot contain another, any currently open paragraph must be closed before starting another.) Because this implication is based on the combination of the DTD and the individual document, it is not usually possible to infer elements from document tags alone but only by using an SGML—or HTML—aware parser with knowledge of the DTD. <a href="/wiki/HTML5" title="HTML5">HTML5</a> creates a similar result by defining what tags can be omitted.<a href="#cite_note-whatwg-syntax-tag-omission-5">[4]</a> <div class="mw-heading mw-heading3"><h3 id="SGML_vs._XML">SGML vs. XML</h3>[<a href="/w/index.php?title=HTML_element&action=edit&section=3" title="Edit section: SGML vs. XML">edit</a>]</div> SGML is complex, which has limited its widespread understanding and adoption. <a href="/wiki/XML" title="XML">XML</a> was developed as a simpler alternative. Although both can use the DTD to specify the supported elements and their permitted combinations as document structure, XML parsing is simpler. The relation from tags to elements is always that of parsing the actual tags included in the document, without the implied closures that are part of SGML.<a href="#cite_note-6">[note 2]</a> HTML as used on the current web is likely to be either treated as XML, by being <a href="/wiki/XHTML" title="XHTML">XHTML</a>, or as <a href="/wiki/HTML5" title="HTML5">HTML5</a>; in either case the parsing of document tags into <a href="/wiki/Document_Object_Model" title="Document Object Model">Document Object Model</a> (DOM) elements is simplified compared to legacy HTML systems. Once the DOM of elements is obtained, behavior at higher levels of interface (example: screen rendering) is identical or nearly so.<a href="#cite_note-8">[note 3]</a> <div class="mw-heading mw-heading3"><h3 id="%block;_vs._box"><code>%block;</code> vs. box</h3>[<a href="/w/index.php?title=HTML_element&action=edit&section=4" title="Edit section: %block; vs. box">edit</a>]</div> Part of this CSS presentation behavior is the notion of the "<a href="/wiki/CSS_box_model" title="CSS box model">box model</a>". This is applied to those elements that CSS considers to be "block" elements, set through the CSS <code class="mw-highlight mw-highlight-lang-css mw-content-ltr" style="" dir="ltr">display: block;</code> declaration. HTML also has a similar concept, although different, and the two are very frequently confused. <code>%block;</code> and <code>%inline;</code> are groups within the HTML DTD that group elements as being either "block-level" or "inline".<a href="#cite_note-W3C,_HTML_4.01,_block_and_inline-9">[6]</a> This is used to define their nesting behavior: block-level elements cannot be placed into an inline context.<a href="#cite_note-10">[note 4]</a> This behavior cannot be changed; it is fixed in the DTD. Block and <a href="/w/index.php?title=Inline_elements&action=edit&redlink=1" class="new" title="Inline elements (page does not exist)">inline elements</a> have the appropriate and different <a href="/wiki/CSS" title="CSS">CSS</a> behaviors attached to them by default,<a href="#cite_note-W3C,_HTML_4.01,_block_and_inline-9">[6]</a> including the relevance of the box model for particular element types. Note though that this CSS behavior can, and frequently is, changed from the default. Lists with <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><ul><li> ...</code> are <code>%block;</code> elements and are presented as block elements by default. However, it is quite common to set these with CSS to display as an inline list.<a href="#cite_note-11">[7]</a> <div class="mw-heading mw-heading2"><h2 id="Overview">Overview</h2>[<a

the content in between. An HTML tag is composed of the name of the element, surrounded by <a href="/wiki/Angle_bracket" class="mw-redirect" title="Angle bracket">angle brackets</a>. An end tag also has a slash after the opening angle bracket, to distinguish it from the start tag. For example, a paragraph, which is represented by the <code class="nowrap" style=""></code> element, would be written as: <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><p>In the HTML syntax, most elements are written ...</p> </pre></div> However, not all of these elements require the end tag, or even the start tag, to be present.<a href="#cite_note-whatwg-syntax-tag-omission-5">[4]</a> Some elements, the so-called <a href="#Void_elements">void elements</a>, do not have an end tag. A typical example is the <code class="nowrap" style=""> </code> (hard line-break) element. A void element's behavior is predefined, and it cannot contain any content or other elements. For example, an address would be written as: <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><p>P. Sherman<br>42 Wallaby Way<br>Sydney</p> </pre></div> When using <a href="/wiki/XHTML" title="XHTML">XHTML</a>, it is required to open and close all elements, including void elements. This can be done by placing an end tag immediately after the start tag, but this is not legal in HTML 5 and will lead to two elements being created. An alternative way to specify that it is a void element, which is compatible with both XHTML and HTML 5, is to put a <code>/</code> at the end of the tag (not to be confused with the <code>/</code> at the beginning of a closing tag). <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><p>P. Sherman<br />42 Wallaby Way<br />Sydney</p> </pre></div> <a href="/wiki/HTML_attribute" title="HTML attribute">HTML attributes</a> are specified inside the start tag. For example, the <code class="nowrap" style=""><abbr></code> element, which represents an <a href="/wiki/Abbreviation" title="Abbreviation">abbreviation</a>, expects a <code>title</code> attribute within its opening tag. This would be written as: <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><abbr title="abbreviation">abbr.</abbr> </pre></div> Informally, HTML elements are sometimes referred to as "tags" (an example of <a href="/wiki/Synecdoche" title="Synecdoche">synecdoche</a>), though many prefer the term tag strictly in reference to the markup delimiting the start and end of an element. Element (and attribute) names may be written in any combination of upper or lower case in HTML, but must be in lower case in XHTML.<a href="#cite_note-XHTML10-42-12">[8]</a> The canonical form was upper-case until <a href="/wiki/HTML_4" class="mw-redirect" title="HTML 4">HTML 4</a>, and was used in HTML specifications, but in recent years, lower-case has become more common. <div class="mw-heading mw-heading4"><h4 id="Types_of_element">Types of element</h4>[<a href="/w/index.php?title=HTML_element&action=edit&section=7" title="Edit section: Types of element">edit</a>]</div> There are three kinds of <a href="/wiki/HTML" title="HTML">HTML</a> elements: normal elements, raw text elements, and void elements. <style data-mw-deduplicate="TemplateStyles:r1238216509">.mw-parser-output .vanchor>:target~.vanchor-text{background-color:#b1d2ff}@media screen{html.skin-theme-clientpref-night .mw-parser-output .vanchor>:target~.vanchor-text{background-color:#0f4dc9}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .vanchor>:target~.vanchor-text{background-color:#0f4dc9}}</style>Normal elements usually have both a start tag and an end tag, although for some elements the end tag, or both tags, can be omitted. It is constructed in a similar way: <ul><li>a start tag (<code class="nowrap" style=""><<var style="padding-right: 1px;">tag</var>></code>) marking the beginning of an element, which may incorporate any number of <a href="/wiki/HTML_attribute" title="HTML attribute">HTML attributes</a>;</li> <li>some amount of content, including text and other elements;</li> <li>an end tag, in which the element name is prefixed with a <a href="/wiki/Slash_(punctuation)" title="Slash (punctuation)">slash</a>: <code class="nowrap" style=""></<var style="padding-right: 1px;">tag</var>></code>.</li></ul> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238216509">Raw text elements (also known as text or text-only elements) are constructed with: <ul><li>a start tag (in the form <code class="nowrap" style=""><<var style="padding-right: 1px;">tag</var>></code>) marking the beginning of an element, which may incorporate any number of HTML attributes;</li> <li>some amount of text content, but no elements (all tags, apart from the applicable end tag, will be interpreted as content);</li> <li>an end tag, in which the element name is prefixed with a slash: <code class="nowrap" style=""></<var style="padding-right: 1px;">tag</var>></code>. In some versions of HTML, the end tag is optional for some elements. The end tag is required in <a href="/wiki/XHTML" title="XHTML">XHTML</a>.</li></ul> An example is the <code class="nowrap" style=""><title></code> element, which must not contain other elements (including markup of text), only plain text. <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238216509">Void elements (also sometimes called empty elements, single elements or stand-alone elements) only have a start tag (in the form <code class="nowrap" style=""><<var style="padding-right: 1px;">tag</var>></code>), which contains any HTML attributes. They may not contain any children, such as text or other elements. For compatibility with <a href="/wiki/XHTML" title="XHTML">XHTML</a>, the HTML specification[<a href="/wiki/Wikipedia:Avoid_weasel_words" class="mw-redirect" title="Wikipedia:Avoid weasel words">which?</a>] allows an optional space and slash[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] (<code class="nowrap" style=""><<var style="padding-right: 1px;">tag</var> /></code> is permissible). The slash is required in <a href="/wiki/XHTML" title="XHTML">XHTML</a> and other <a href="/wiki/XML" title="XML">XML</a> applications. Two common void elements are <code class="nowrap" style=""> </code> (for a <a href="/wiki/Hard_return" class="mw-redirect" title="Hard return">hard line-break</a>, such as in a poem or an address) and <code class="nowrap" style=""><hr /></code> (for a thematic break). Other such elements are often place-holders which reference external files, such as the image (<code class="nowrap" style=""><img /></code>) element. The attributes included in the element will then point to the external file in question. Another example of a void element is <code class="nowrap" style=""><link /></code>, for which the syntax is: <div class="mw-highlight mw-highlight-lang-html mw-content-ltr" dir="ltr"><pre><link rel="stylesheet" href="fancy.css" type="text/css"> </pre></div> This <code class="nowrap" style=""><link /></code> element points the browser at a <a href="/wiki/Style_sheet_(web_development)" title="Style sheet (web development)">style sheet</a> to use when presenting the HTML document to the user. In the HTML syntax attributes do not have to be quoted if they are composed only of certain characters: letters, digits, the hyphen-minus and the period. When using the XML syntax (XHTML), on the other hand, all attributes must be quoted, and a spaced trailing <a href="/wiki/Slash_(punctuation)" title="Slash (punctuation)">slash</a> is required before the last angle bracket: <div class="mw-highlight mw-highlight-lang-xml mw-content-ltr" dir="ltr"><pre><link rel="stylesheet" href="fancy.css" type="text/css" /> </pre></div> <div class="mw-heading mw-heading4"><h4 id="Attributes">Attributes</h4>[<a href="/w/index.php?title=HTML_element&action=edit&section=8" title="Edit section: Attributes">edit</a>]</div> <a href="/wiki/HTML_attribute" title="HTML attribute">HTML attributes</a> define desired behavior or indicate additional element properties. Most attributes require a value. In HTML, the value can be left unquoted if it does not include spaces (<code><var style="padding-right: 1px;">attribute</var>=<var style="padding-right: 1px;">value</var></code>), or it can be quoted with single or double quotes (<code><var style="padding-right: 1px;">attribute</var>='<var style="padding-right: 1px;">value</var>'</code> or <code><var style="padding-right: 1px;">attribute</var>="<var style="padding-right: 1px;">value</var>"</code>). In <a href="/wiki/XML" title="XML">XML</a>, those quotes are required. <a href="/wiki/Boolean_data_type" title="Boolean data type">Boolean</a> attributes, on the other hand, do not require a value to be specified.

Other user agents may not recognize non-standard elements, and they will be ignored, possibly causing the page to be displayed improperly. In 1998, <a href="/wiki/XML" title="XML">XML</a> (a simplified form of SGML) introduced mechanisms to allow anyone to develop their own elements and incorporate them in <a href="/wiki/XHTML" title="XHTML">XHTML</a> documents, for use with XML-aware user agents.<a href="#cite_note-13">[9]</a> Subsequently, HTML 4.01 was rewritten in an <a href="/wiki/XML" title="XML">XML</a>-compatible form, <a href="#XHTML10">XHTML 1.0</a> (eXtensible HTML). The elements in each are identical, and in most cases valid XHTML 1.0 documents will be valid or nearly valid HTML 4.01 documents. This article mainly focuses on real HTML, unless noted otherwise; however, it remains applicable to XHTML. See <a href="/wiki/HTML#SGML-based_versus_XML-based_HTML" title="HTML">HTML</a> for a discussion of the minor differences between the two. <div class="mw-heading mw-heading3"><h3 id="Element_status">Element status</h3>[<a href="/w/index.php?title=HTML_element&action=edit&section=10" title="Edit section: Element status">edit</a>]</div> Since the first version of HTML, several elements have become outmoded, and are <a href="/wiki/Deprecated" class="mw-redirect" title="Deprecated">deprecated</a> in later standards, or do not appear at all, in which case they are invalid (and will be found invalid, and perhaps not displayed, by <a href="/wiki/XML_validation" title="XML validation">validating</a> user agents).<a href="#cite_note-XML10-51-14">[10]</a> In <a href="/wiki/HTML_4.01" class="mw-redirect" title="HTML 4.01">HTML 4.01</a> / <a href="/wiki/XHTML_1.0" class="mw-redirect" title="XHTML 1.0">XHTML 1.0</a>, the status of elements is complicated by the existence of three types of <a href="/wiki/Document_Type_Definition" class="mw-redirect" title="Document Type Definition">DTD</a>: <ul><li>Transitional, which contain deprecated elements, but which were intended to provide a transitional period during which authors could update their practices;</li> <li>Frameset, which are versions of the Transitional DTDs which also allow authors to write frameset documents;</li> <li>Strict, which is the up-to-date (as at 1999) form of HTML.</li></ul> HTML5 instead provides a listing of obsolete features to go along with the standardized normative content. They are broken down into "obsolete but conforming" for which implementation instructions exist and "non-conforming" ones that should be replaced.<a href="#cite_note-15">[11]</a> The first Standard (<a href="/wiki/HTML#HTML_2" title="HTML">HTML 2.0</a>) contained four deprecated elements, one of which was invalid in <a href="/wiki/HTML_3.2" class="mw-redirect" title="HTML 3.2">HTML 3.2</a>. All four are invalid in <a href="/wiki/HTML_4" class="mw-redirect" title="HTML 4">HTML 4.01 Transitional</a>, which also deprecated a further ten elements. All of these, plus two others, are invalid in <a href="/wiki/HTML_4" class="mw-redirect" title="HTML 4">HTML 4.01 Strict</a>. While the frame elements are still current in the sense of being present in the Transitional and Frameset DTDs, there are no plans to preserve them in future standards, as their function has been largely replaced, and they are highly problematic for user accessibility. (Strictly speaking, the most recent XHTML standard, <a href="/wiki/XHTML_1.1" class="mw-redirect" title="XHTML 1.1">XHTML 1.1</a> (2001), does not include frames at all; it is approximately equivalent to <a href="/wiki/XHTML_1.0" class="mw-redirect" title="XHTML 1.0">XHTML 1.0 Strict</a>, but also includes the <a href="/wiki/Ruby_(annotation_markup)" class="mw-redirect" title="Ruby (annotation markup)">Ruby markup</a> module.)<a href="#cite_note-XHTML11-16">[12]</a> A common source of confusion is the loose use of deprecated to refer to both deprecated and invalid status, and to elements that are expected to be formally deprecated in the future. <div class="mw-heading mw-heading3"><h3 id="Content_vs._presentation_and_behavior">Content vs. presentation and behavior</h3>[<a href="/w/index.php?title=HTML_element&action=edit&section=11" title="Edit section: Content vs. presentation and behavior">edit</a>]</div> Since HTML 4, HTML has increasingly focused on the separation of content (the visible text and images) from presentation (like color, font size, and layout).<a href="#cite_note-17">[13]</a> This is often referred to as a <a href="/wiki/Separation_of_concerns" title="Separation of concerns">separation of concerns</a>. HTML is used to represent the structure or content of a document, its presentation remains the sole responsibility of <a href="/wiki/CSS" title="CSS">CSS</a> style sheets. A default <a href="/wiki/Style_sheet_(web_development)" title="Style sheet (web development)">style sheet</a> is suggested as part of the CSS standard, giving a default rendering for HTML.<a href="#cite_note-18">[14]</a> Behavior (interactivity) is also kept separate from content, and is handled by <a href="/wiki/Client-side_scripting" class="mw-redirect" title="Client-side scripting">scripts</a>. Images are contained in separate <a href="/wiki/Graphics" title="Graphics">graphics</a> files, separate from text, though they can also be considered part of the content of a page. Separation of concerns allows the document to be presented by different user agents according to their purposes and abilities. For example, a user agent can select an appropriate style sheet to present a document by displaying on a monitor, printing on paper, or to determine speech characteristics in an audio-only user agent. The structural and semantic functions of the markup remain identical in each case. Historically, user agents did not always support these features. In the 1990s, as a stop-gap, presentational elements (like <code class="nowrap" style=""></code> and <code class="nowrap" style=""></code>) were added to HTML, at the cost of creating problems for interoperability and user accessibility. This is now regarded as outmoded and has been superseded by style sheet-based design; most presentational elements are now deprecated.<a href="#cite_note-HTML401-141-19">[15]</a> External image files are incorporated with the <code class="nowrap" style=""><img /></code> or <code class="nowrap" style=""><object /></code> elements.

While all elements are part of the document sequence, block elements appear within their parent elements: <ul><li>as rectangular objects which do not break across lines;</li> <li>with block margins, width, and height properties which can be set independently of the surrounding elements.</li></ul> Conversely, inline elements are treated as part of the flow of document text; they cannot have margins, width, or height set, and do break across lines. <div class="mw-heading mw-heading3"><h3 id="Block_elements">Block elements</h3>[<a href="/w/index.php?title=HTML_element&action=edit&section=15" title="Edit section: Block elements">edit</a>]</div> Block elements, or block-level elements, have a rectangular structure. By default, these elements will span the entire width of its parent element, and will thus not allow any other element to occupy the same horizontal space as it is placed on. The rectangular structure of a block element is often referred to as the <a href="/wiki/File:W3C_and_Internet_Explorer_box_models.svg" title="File:W3C and Internet Explorer box models.svg">box model</a>, and is made up of several parts. Each element contains the following: <ul><li>The content of an element is the actual text (or other media) placed between the opening and closing tags of an element.</li> <li>The padding of an element is the space around the content but which still forms part of the element. Padding should not be used to create white space between two elements. Any background style assigned to the element, such as a background image or color, will be visible within the padding. Increasing the size of an element's padding increases the amount of space this element will take up.</li> <li>The border of an element is the absolute end of an element and spans the perimeter of that element. The thickness of a border increases the size of an element.</li> <li>The margin of an element is the white space that surrounds an element. The content, padding, and border of any other element will not be allowed to enter this area unless forced to do so by some advanced <a href="/wiki/CSS" title="CSS">CSS</a> placement. Using most standard <a href="/wiki/Document_Type_Definition" class="mw-redirect" title="Document Type Definition">DTDs</a>, margins on the left and right of different elements will push each other away. Margins on the top or bottom of an element, on the other hand, will not stack or will intermingle. This means that the white space between these elements will be as big as the larger margin between them.</li></ul> The above section refers only to the detailed implementation of CSS rendering and has no relevance to HTML elements themselves. <div class="mw-heading mw-heading4"><h4 id="Basic_text">Basic text</h4>[<a href="/w/index.php?title=HTML_element&action=edit&section=16" title="Edit section: Basic text">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1228772891"> <dl class="glossary"> <dt id="p"><dfn><code class="html" title="Paragraph" style="font-size:116%;"><p>... </code></dfn></dt> <dd>Creates a paragraph, perhaps the most common block level element.</dd> <dd><code>P</code> existed in <a href="#HTMLTAGS">HTML Tags</a>, and was standardized in <a href="#HTML20">HTML 2.0</a>; still current.</dd> <dt id="h1"><dfn><code class="html" title="Level 1 heading" style="font-size:116%;"><h1>...</h1> </code> </dfn></dt> <dt id="h2"><dfn><code class="html" title="Level 2 heading" style="font-size:116%;"><h2>...</h2> </code></dfn></dt> <dt id="h3"><dfn><code class="html" title="Level 3 heading" style="font-size:116%;"><h3>...</h3> </code></dfn></dt> <dt id="h4"><dfn><code class="html" title="Level 4 heading" style="font-size:116%;"><h4>...</h4> </code></dfn></dt> <dt id="h5"><dfn><code class="html" title="Level 5 heading" style="font-size:116%;"><h5>...</h5> </code></dfn></dt> <dt id="h6"><dfn><code class="html" title="Level 6 heading" style="font-size:116%;"><h6>...</h6> </code></dfn></dt> <dd>Section headings at different levels. <code>h1</code> delimits the highest-level heading, <code>h2</code> the next level down (sub-section), <code>h3</code> for a level below that, and so on to <code>h6</code>.

When users view the web page in a browser, they can click the text to activate the link and visit the page whose URL is in the link.<a href="#cite_note-29">[25]</a> In HTML, an "anchor" can be either the origin (the <a href="/wiki/Anchor_text" title="Anchor text">anchor text</a>) or the target (destination) end of a <a href="/wiki/Hyperlink" title="Hyperlink">hyperlink</a>. As an origin, setting the attribute <code>href</code>,<a href="#cite_note-30">[26]</a> creates a hyperlink; it can point to either another part of the document or another resource (e.g. a webpage) using an external <a href="/wiki/Uniform_Resource_Locator" class="mw-redirect" title="Uniform Resource Locator">URL</a>. As a target, setting the <code>name</code> or <code>id</code> <a href="/wiki/HTML_attributes" class="mw-redirect" title="HTML attributes">HTML attributes</a>, allows the element to be linked from a <a href="/wiki/Uniform_Resource_Locator" class="mw-redirect" title="Uniform Resource Locator">Uniform Resource Locator</a> (URL) via a <a href="/wiki/Fragment_identifier" class="mw-redirect" title="Fragment identifier">fragment identifier</a>. The two forms, origin and anchor, can be used concurently. In HTML5, any element can now be made into a target by using the <code>id</code> attribute,<a href="#cite_note-31">[27]</a> so using <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><a name="foo">...</a></code> is not necessary, although this way of adding anchors continues to work. To illustrate: the header of a table of contents section on <samp>example.com</samp>'s homepage could be turned into a target by writing: <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><h2><a name="contents">Table of contents</a></h2></code>. Continuing with this example, now that the section has been marked up as a target, it can be referred to from external sites with a link like: <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><a href="http://example.com#contents">see contents</a></code>; or with a link on the same page like: <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><a href="#contents">contents, above</a></code>. The attribute <code>title</code> may be set to give brief information about the link: <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><a href="URL" title="additional information">link text</a></code>. In most graphical browsers, when the cursor hovers over a link, the cursor changes into a hand with an extended index finger and the <code>title</code> value is displayed in a <a href="/wiki/Tooltip" title="Tooltip">tooltip</a> or in some other manner. Some browsers render <a href="/wiki/Alt_attribute" title="Alt attribute">alt text</a> the same way, although this is not what the specification calls for.</dd> <dd><code>A</code> existed in <a href="#HTMLTAGS">HTML Tags</a>, and was standardized in <a href="#HTML20">HTML 2.0</a>;</dd> </dl> <div class="mw-heading mw-heading4"><h4 id="Phrase_elements">Phrase elements</h4>[<a href="/w/index.php?title=HTML_element&action=edit&section=21" title="Edit section: Phrase elements">edit</a>]</div> Phrase elements are used for marking up phrases and adding structure or semantic meaning to text fragments.

In HTML 4 and earlier, <code class="nowrap" style=""><cite></code> was for "a citation or a reference to other sources" without any particular limitations or requirements.<a href="#cite_note-40">[36]</a> The <a href="/wiki/W3C" class="mw-redirect" title="W3C">W3C</a> HTML 5 spec uses a refinement of this idea, reflecting how the element has historically been used, but now requiring that it contain (but not be limited to) at least one of "the title of the work or the name of the author (person, people or organization) or an URL reference, or a reference in abbreviated form as per the conventions used for the addition of citation metadata."<a href="#cite_note-41">[37]</a> But the WHATWG spec only permits the element to be used around the title of a work.<a href="#cite_note-42">[38]</a> The W3C specs began with the broader definition, then switched to the very narrow one after WHATWG made this change. However, W3C reverted their own change in 2012, in response to negative developer-community feedback; the element was in broadly-deployed use with the broader scope, e.g., various blog and forum platforms wrap commenters' IDs and e-mail addresses in <code class="nowrap" style=""><cite>...</cite></code>, and people using the element for bibliographic citations were (and still are) routinely wrapping each entire citation in this element. Another problem with the element is that WHATWG recommends that it be italicized by default (thus almost all browsers do so), because it (in their view) is only for publication titles. By convention, however, only certain kinds of titles actually take italics, while others are expected to be put in quotation marks, and standards may actually vary by publishing context and language. Consequently, many website authors and admins use a site-wide stylesheet to undo this element's auto-italics. </dd> <dt id="data"><dfn><code class="html" title="Data" style="font-size:116%;"><data>...</data> </code></dfn></dt> <dd>Links inline content with a machine-readable translation.</dd> <dd>Standardized in <a href="#HTML5">HTML5</a>.<a href="#cite_note-43">[39]</a></dd> <dt id="del"><dfn><code class="html" title="Deleted" style="font-size:116%;"><del>...</del> </code></dfn></dt> <dd>Deleted text.

Unlike most HTML tags, comments do not nest. More generally, there are some strings that are not allowed to appear in the comment text. Those are <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"></code>(this ends the comment so it trivially follows it can not appear inside it) and <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr">--!></code>.

Comments can appear anywhere in a document, as the HTML parser is supposed to ignore them no matter where they appear so long as they are not inside other HTML tag structures (i.e., they cannot be used next to attributes and values; this is invalid markup: <code> style="..."></code>). Comments can even appear before the doctype declaration; no other tags are permitted to do this. However, not all browsers and HTML editors are fully compliant with the HTML syntax framework and may do unpredictable things under some syntax conditions. Defective handling of comments only affects about 5% of all browsers and HTML editors in use, and even then only certain versions are affected by comment mishandling issues (Internet Explorer 6 accounts for most of this high percentage). There are a few compatibility quirks involving comments: <ul><li>Placing comments – or indeed any characters except for white-space – before the <code>doctype</code> will cause Internet Explorer 6 to use <a href="/wiki/Quirks_mode" title="Quirks mode">quirks mode</a> for the HTML page. None of the <code>doctype</code> information will be processed.</li> <li>For compatibility with some pre-1995 browsers, the contents of <code class="nowrap" style=""><style></code> and <code class="nowrap" style=""><script></code> elements are still sometimes surrounded by comment delimiters, and CSS- and script-capable browsers are written to specifically ignore that comment markup as not actually a comment. This means that attempts to actually comment out CSS and script markup by change the elements inside the comment to not be recognized, e.g. <code><-- [script]...[/script] --></code>.</li> <li>The <a href="/wiki/BlueGriffon" title="BlueGriffon">BlueGriffon</a> HTML editor, in versions 1.7.<var style="padding-right: 1px;">x</var>, makes comments that are not embedded in the syntax structure; <code class="mw-highlight mw-highlight-lang-html mw-content-ltr" style="" dir="ltr"><style> ... {comment tags} ...</style></code> will show up on-screen.
