HTML restriction/nan

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 option. 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:


 * – allows pre-defined HTML snippets with.
 * – allows for adding HTML from a set of tags and attributes defined in the wiki's settings.
 * – adds 'Secret key' protection for html sections.
 * – Ún-tsún tsí-tī bīng-miâ khong-kan lāi-té ê guān-su HTML
 * – allows for defining HTML- and JavaScript-based "widgets", with optional parameters.
