finiki:Interface administrators

Interface administrators can edit CSS/JS pages that they do not own (that is, any page ending with .css or .js that is either in the MediaWiki: namespace or is another user's user subpage). In particular, they have the ability to edit sitewide CSS/JS pages (pages such as MediaWiki:Common.js or MediaWiki:Vector.css). These pages are executed by the browser of wiki editors and readers as code, which can be used to change how content is styled, change the behavior of pages, or even create highly complex tools. In addition, they can also edit all other pages in the MediaWiki namespace.
