HTML hān-tsè

This page is a translated version of the page HTML restriction and the translation is 7% complete.

MediaWiki restricts the use of HTML by default. Only some HTML elements and attributes are allowed. Raw-HTML sections, surrounded by the "html" tag, can be enabled with the configuration parameter $wgRawHtml . The code is available at includes/parser/Sanitizer.php.

Wikimedia websites (see complete list here) do not allow full use of HTML. A request to allow full use of HTML was rejected in 2005.

There are several extensions that allow for the inclusion of raw HTML. Here are the extensions that appear to be safe:

Extension Status Description
Extension:HTMLets unmaintained allows pre-defined HTML snippets with $wgRawHtml = false;
