Editing HTML element (section)

==Document body elements==

In visual browsers, displayable elements can be rendered as either ''block'' or ''inline''. While all elements are part of the document sequence, block elements appear within their parent elements:
* as rectangular objects which do not break across lines;
* with block margins, width, and height properties which can be set independently of the surrounding elements.
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.

===Block elements===

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 [[:File: W3C and Internet Explorer box models.svg|box model]], and is made up of several parts. Each element contains the following:
* The '''content''' of an element is the actual text (or other media) placed between the opening and closing tags of an element.
* 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.
* 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.
* 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 [[CSS]] placement. Using most standard [[Document Type Definition|DTDs]], 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.

The above section refers only to the detailed implementation of CSS rendering and has no relevance to HTML elements themselves.

====Basic text====

{{glossary}}
{{term|term=p |content= {{XMLElement|p|Paragraph}} }}
{{defn|1= Creates a paragraph, perhaps the most common block level element.}}

{{term|term=h5 |content= {{XMLElement|h5|Level 5 heading}} |multi=y}}
{{term|term=h6 |content= {{XMLElement|h6|Level 6 heading}} |multi=y}}

{{defn|1= 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>. They are sometimes referred to collectively as <code>h''n''</code> tags, ''n'' meaning any of the available heading levels.

Most visual browsers show headings as large bold text by default, though this can be overridden with [[Cascading Style Sheets|CSS]]. Heading elements are not intended merely for creating large or bold text – in fact, they should {{em|not}} be used for explicitly styling text. Rather, they describe the document's structure and organization. Some programs use them to generate outlines and tables of contents.

{{glossary end}}

===Inline elements===

Inline elements cannot be placed directly inside the {{code|lang=html|code=<body>}} element; they must be wholly nested within block-level elements.<ref>{{citation|url=http://www.w3.org/TR/html401/struct/global.html#h-7.5.1 |title=HTML 4.01 |publisher=W3C |access-date=2012-03-26}}</ref>

====Anchor====
{{for|anchors on Wikipedia|WP:ANCHOR DEF|selfref=true}}
{{glossary}}
{{term|term=a |content= {{XMLElement|a|Anchor}} }}
{{defn|1= <p>An anchor element is called an anchor because web designers can use it to "anchor" a URL to some text on a web page. 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.<ref>{{cite book |last1= Tittel |first1= Ed |last2= Burmeister |first2= Mary C. |date= 2005 |title= HTML 4 for dummies |edition= 5th |publisher= Wiley |location= Hoboken, New Jersey |isbn= 978-0-7645-8917-1 |page= 96 |url= https://archive.org/details/html4fordummies00titt_2/page/96/ |url-access= registration |access-date= 7 August 2022}}</ref></p>

<p>In HTML, an "anchor" can be either the {{em|origin}} (the [[anchor text]]) or the {{em|target}} (destination) end of a [[hyperlink]]. As an origin, setting the attribute <code>href</code>,<ref>{{cite web|url=http://www.w3.org/Provider/ServerWriter.html|title=ServerWriter -- /Provider|website=W3C}}</ref> creates a hyperlink; it can point to either another part of the document or another resource (e.g. a webpage) using an external [[Uniform Resource Locator|URL]]. As a target, setting the <code>name</code> or <code>id</code> [[HTML attributes]], allows the element to be linked from a [[Uniform Resource Locator]] (URL) via a [[fragment identifier]]. The two forms, origin and anchor, can be used concurrently.</p>

In HTML5, any element can now be made into a target by using the <code>id</code> attribute,<ref>{{cite web|url=http://www.w3.org/tr/html5/index.html#attributes-1|title=HTML 5.2|website=W3C}}</ref> so using {{code|lang=html|code=<a name="foo">...</a>}} is not necessary, although this way of adding anchors continues to work.</p>

<p>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|lang=html|code=<h2><a name="contents">Table of contents</a></h2>}}.</p>

<p>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|lang=html|code=<a href="http://example.com#contents">see contents</a>}};</p>

<p>or with a link on the same page like: {{code|lang=html|code=<a href="#contents">contents, above</a>}}.</p>

<p>The attribute <code>title</code> may be set to give brief information about the link: {{code|lang=html|code=<a href="URL" title="additional information">link text</a>}}.</p>

<p>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 [[tooltip]] or in some other manner. Some browsers render [[Alt attribute|alt text]] the same way, although this is not what the specification calls for.</p>

====Phrase elements====
Phrase elements are used for marking up phrases and adding structure or semantic meaning to text fragments. For example, the {{tag|em|o}} and {{tag|strong|o}} tags can be used for adding emphasis to text.

These elements are useful primarily for documenting computer code development and user interaction through differentiation of source code ({{code|lang=html|code=<code>}}), variables ({{code|lang=html|code=<var>}}), user input ({{code|lang=html|code=<kbd>}}), and terminal or other output ({{code|lang=html|code=<samp>}}).

====Presentation====
As visual presentational markup only applies directly to visual browsers, its use is discouraged. Style sheets should be used instead. Several of these elements are deprecated or invalid in HTML 4 / XHTML 1.0, and the remainder are invalid in the current draft of [http://www.w3.org/TR/2005/WD-xhtml2-20050527/ XHTML 2.0]. The current draft of [https://web.archive.org/web/20150801133040/http://www.w3.org/TR/html5/text-level-semantics.html HTML5], however, re-includes {{tag|s|o}}, {{tag|u|o}}, and {{tag|small|o}}, assigning new semantic meaning to each. In an [[HTML5]] document, the use of these elements is no longer discouraged, provided that it is semantically correct.

{{term|term=b |content= {{XMLElement|b|Keyword}} }}
{{defn|1= <!-- not deprecated in [[HTML 4.01]]; not included in [[XHTML 2.0]] which is in draft stage; now a semantic element in [[HTML5]] -->
In [[HTML 4]], set font to '''boldface''' where possible. Equivalent CSS: {{code|lang=css|code={ font-weight: bold; } }}. The {{tag|strong|o}} element usually has the same effect in visual browsers, as well as having more semantic meaning, under [[HTML 4.01]].

In [[HTML5]], however, {{tag|b|o}} has its own meaning, distinct from that of {{tag|strong|o}}. It denotes "text to which attention is being drawn for utilitarian purposes without conveying any extra importance and with no implication of an alternate voice or mood."<ref name="html5-b-element">{{citation|url=http://developers.whatwg.org/text-level-semantics.html#the-b-element |title=4.6 Text-level semantics — The b element |publisher=Developers.whatwg.org |access-date=2012-03-26}}</ref>

{{defn|1= <!-- not deprecated in HTML 4.01; not included in XHTML 2.0 which is in draft stage; now a semantic element in HTML5 -->
In [[HTML 4]], set font to ''italic'' where possible. Equivalent [[CSS]]: {{code|lang=css|code={ font-style: italic; } }}. Using {{tag|em}} has the same visual effect in most browsers, as well as having a semantic meaning as ''emphasis'', under [[HTML 4.01]]. (Purely typographic italics have many non-emphasis purposes, as HTML 5 more explicitly recognized.)

In [[HTML5]], however, {{tag|i|o}} has its own semantic meaning, distinct from that of {{tag|em|o}}. It denotes "a different quality of text" or "an alternate<!--sic--> voice or mood" e.g., a thought, a ship name, a [[Binomial nomenclature|binary species name]], a foreign-language phrase, etc.<!-- Not (or no longer) a precise quote, so don't put this in quotation marks --><ref name="html5-i-element">{{citation|url=http://developers.whatwg.org/text-level-semantics.html#the-i-element |title=4.6 Text-level semantics — The i element |publisher=Developers.whatwg.org |access-date=2012-03-26}}</ref>

In [[HTML5]], the {{tag|u|o}} element denotes "a span of text with an unarticulated, though explicitly rendered, non-textual annotation, such as labelling the text as being a proper name in Chinese text (a Chinese proper name mark), or labelling the text as being misspelt." The [[HTML5]] specification reminds developers that other elements are almost always more appropriate than {{tag|u|o}} and admonishes designers not to use underlined text where it could be confused for a hyper-link.<ref name="html5-u-element">{{citation|url=http://developers.whatwg.org/text-level-semantics.html#the-u-element |title=4.6 Text-level semantics — The u element |publisher=Developers.whatwg.org |access-date=2012-03-26}}</ref>

Can specify the font color with the <code>color</code> attribute (note the American spelling), typeface with the <code>face</code> attribute, and absolute or relative size with the <code>size</code> attribute.

Examples (all uses are deprecated, use CSS equivalents if possible):
* {{code|lang=html|code=<font color="green">text</font>}} creates {{green|green text}}.
* {{code|lang=html|code=<font color="#114499">text</font>}} creates <span style="color:#149;">text with [[Hex triplet|hexadecimal color]] #114499</span>.
* {{code|lang=html|code=<font size="4">text</font>}} creates <span style="font-size:140%;">text</span> with size 4. Sizes are from 1 to 7. The standard size is 3, unless otherwise specified in the &lt;body> or other tags.
* {{code|lang=html|code=<font size="+1">text</font>}} creates <span style="font-size:125%;">text with size 1 bigger than the standard.</span> {{code|lang=html|code=<font size="-1">text</font>}} is opposite.
* {{code|lang=html|code=<font face="Courier">text</font>}} makes <span style="font-family:Courier;">text</span> with Courier font.

Equivalent CSS for font attributes:
*<code class="mw-highlight"><span class="p">&lt;</span><span class="nt">font</span> <span class="na">size</span><span class="o">=</span><span class="s">"<var>N</var>"</span><span class="p">&gt;</span></code> corresponds to <code class="mw-highlight"><span class="p">{</span><span class="nb">font-size</span><span class="o" style="color: #666;">:</span> <span class="nb"><var>Y</var><var>units</var></span><span class="p">}</span></code> (the HTML specification does not define the relationship between size <var>N</var> and unit-size <var>Y</var>, nor does it define a unit).
*{{code|lang=html|code=<font color="red">}} corresponds to {{code|lang=css|code={ color: red; } }}
*{{code|lang=html|code=<font face="Times New Roman">}} corresponds to {{code|lang=css|code={ font-family: 'Times New Roman', Times, serif; } }} – CSS supports a [[font stack]], of two or more alternative fonts.

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 {{tag|cite}}, 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.

These elements can be combined into a form or in some instances used separately as user-interface controls; in the document, they can be simple HTML or used in conjunction with Scripts.

However, some form of scripts ([[server-side script|server-side]], client-side, or both) must be used to process the user's input once it is submitted.

(These elements are either block or inline elements, but are collected here as their use is more restricted than other inline or block elements.)

===Tables===
The format of HTML Tables was proposed in the [[#HTML30|HTML 3.0 Drafts]] and the later RFC 1942 ''[[#HTMLTABLES|HTML Tables]]''. They were inspired by the [[CALS Table Model]]. Some elements in these proposals were included in HTML 3.2; the present form of HTML Tables was standardized in HTML 4. (Many of the elements used within tables are neither ''block'' nor ''inline'' elements.)
