For many HTML elements, more convenient wikitext code is available, see [[Help:Editing]]. On the other hand, HTML tags allow an <tt>id</tt> that can be referenced in one's [[Help:User style|user style]] cssCSS, and allows the tag to be used as link target.

Line 106:

== Tags ==

{{mlw|HTML_elementHTML element|Span element|<code>'''&lt;span>'''</code>}} is a generic inline text container.

<code>'''&lt;font>'''</code> is a similar tag which is [[w:Deprecationdeprecation|deprecate]]d (should not be used) in favor of <nowiki><span></nowiki>.''

For example

Line 119:

</source>

See also {{tim|font size demo}} and [[metam:Help:Text color]].

It's pointless to combine the legacy tag <tt>&lt;font&gt;</tt>

Line 140:

* <nowiki></div></nowiki> should be preceded by a newline

*<nowiki></div></nowiki> followed by text on the same line, two newlines and text before <nowiki><div></nowiki> on the same line should be avoided (because the two newlines only produce a space)

Example:

{{xpdplain|

--|--|

|o

p<|div>q<|/div>r

s<|div>|t|

|u|

|v|

|x<|/div>y

s<|div>|t|

|u|

|v|

|x<|/div>y

z|

|--|--|

}}

===HTML comment===

Line 167 ⟶ 145:

*{{xpd|t}}

*"<code><nowiki>{{subst:xpd|t}}</nowiki>"</code> gives "&lt;!--t-->start-pqr-end", producing HTML code without the comment.

The "Remove comments" option of [[mw:Extension:ExpandTemplates|ExpandTemplates]] selects whether comments are removed, not just in the final result but throughout the expansion process. This affects the result of parser functions: a comment in the expression of #expr or in the condition of #ifexpr gives an error message unless "Remove comments" is on, and comments affect #if and #ifeq.

Example:

Line 275 ⟶ 253:

* HTML 4.01 specification: [http://www.w3.org/TR/html401/index/elements.html elements] | [http://www.w3.org/TR/html401/index/attributes.html attributes]

* For customizing the handling of HTML in MediaWiki, see the HTML and Tidy sections in [[mw:Manual:Configuration settings]]

* Some extensions allow adding arbitrary HTML to a page, for example [[mw:Extension:AddHTML]],[[mw:Extension:SecureHTML]] and [[mw:Extension:Secure HTML]]; see [http[mw://www.mediawiki.org/wiki/Manual:%24wgRawHtml $wgRawHtml|$wgRawHtml]] for a more complete list

* Within the MediaWiki codebase, these HTML checks happen in [http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/includes/Sanitizer.php includes/Sanitizer.php]
