Board Thread:Support Requests - Designing Your Wikia/@comment-35096338-20140512170253/@comment-856287-20140512174204

I believe it is technically possible, but only by using messy hacks that you shouldn't use; when the site is accessed on mobile, it doesn't even try to load CSS or JS from the normal sources like Special:CSS or MediaWiki:Common.js. Even if it was easy, you still wouldn't want to do it. Everything on every wiki will work MUCH better if you simply respect the mobile skin as it is and work with it. Standards-based design is much, MUCH better. Whenever you make something weird, hacky, and unpredictable, you are making people not like it and go elsewhere 😉

Is there anything in particular you need to "fix" on mobile, or do you just want to make a theme to match the style of the desktop site?
