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

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.
