Extension:GlobalCssJs

Usage
This extension allows loading of global css and js from a central wiki (good for use on wiki farms). Both overall CSS/JS can be added (via MediaWiki:Global.css and MediaWiki:Global.js on the central wiki), as well as user CSS/JS. In order for the global site CSS/JS to work, the local site CSS/JS must be enabled for each respective function to work. In order for the global user CSS/JS to work, the user must have the same username on the local wiki and the central wiki, they must have enabled the "Enable Global User CSS/JS" in their Special:Preferences, and the user CSS and/or JS must be enabled on the local wiki for each respective function to work as well.

You can set the preference for user css/js to be automatically enabled, but it is not recommended to do so on wikis without a shared user database, as it opens up a potential XSS vector, which allows other users to hijack the user's account, among other things.
