MediaWiki is able to parse some HTML tags in wikitext. Brackets for other tags are escaped and the tags are displayed instead of being parsed.

Deprecated tags
[edit]The following tags are parsed by MediaWiki, but they are obsolete in HTML 5. They should be replaced with one of above tags.
You might add a style attribute to reproduce the expected display.
| Tag | Allowed since… | Emits Lint error? | Notes |
|---|---|---|---|
<center>
|
1.1 | Yes | |
<font>
|
1.1 | Yes | |
<rb>
|
1.1 | No | |
<rtc>
|
1.24 | No | |
<strike>
|
1.1 | Yes | |
<tt>
|
1.1 | Yes |
Use cases
[edit]Anchor
[edit]To create a linkable anchor, you can use any HTML tag with an id attribute.
E.g. <span id="note2"></span> allows you to create a link to its location on the page using [[#note2|See relevant note]].
CSS formatting
[edit]With style attribute
[edit]Using HTML tag instead of wikitext equivalent allows you to add a style attribute to define a custom display through CSS language.
With class and id attributes
[edit]Thanks to TemplateStyles, you may add a custom stylesheet to the document.
So it is useful to add class or id attributes to the elements you want to customize their display.
Overridden HTML syntax
[edit]HTML comments
[edit]Wikitext uses HTML comment syntax for its own comments. These comments are ignored by the parser and are not included in the output HTML — not even as HTML comments.
<!-- This text is a wikitext comment. After saving, it will be kept in wikitext source but will not be displayed, neither rendered in HTML source. -->
Pre tag
[edit]The content of a pre tag is not parsed, as in a <nowiki> tag.
You have to use the equivalent wikitext syntax to allow the content parsing. i.e. start each line with a blank space:
Some preformatted text which can contain wikitext, i.e. ''this idiomatic text'' will be parsed. Other line.
to output:
Some preformatted text which can contain wikitext, i.e. this idiomatic text will be parsed. Other line.
