However, you must embed your html within the

Is enabling raw HTML necessary?
Some HTML tags are permitted in wikitext, even with
See m:Help:HTML in wikitext.
The vast majority of fancy formatting seen on Wikimedia sites is achieved using these limited tags (e.g. tables with CSS style tags).
If you can make do with these limitations (leave
$wgRawHtml=false), your wiki will be more secure.
Also note that the "limited" wiki syntax is actually a deliberate design feature of wikis. It is a compact simplified markup which is easily understood even by non-technical users, easily visualised in diff displays, and discourages stylistic tinkering in favor of getting on with writing useful/interesting text.
There are a number of extensions which promise to allow more HTML flexibility, while improving the security situation.
Some require setting
$wgRawHtml=true in conjunction with using the extension, while others offer an alternative.
- Extension:SaferHTMLTag – Allows only sysops and certain user groups to edit pages containing the
- Extension:NamespaceHTML - allows HTML in specific namespaces.
- Extension:Secure HTML – adds "secret key" protection for html sections.
- Extension:HTMLets – allows pre-defined HTML snippets with
- Extension:Widgets – allows HTML and Smarty PHP templates, ostensibly in the form of "widgets", but it can do nearly anything else too.

Do not be tempted to develop an extension which allows arbitrary HTML, otherwise the same serious security issues apply as with setting
