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.

HTML tags deprecated in MediaWiki

‎<rtc> 1.24 No
‎<strike> 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: the parser ignores them, they are not rendered in resulting HTML source.

<!-- 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.
