MediaWiki Common.css worked great,

But look like I use MediaWiki:Mobile.css for Mobile css changes. That'll work.

Similar question: Where do I insert tags? ie.. 

I tried using Mediawiki:common.js, but I see no code appear in the header when I view source. Somewhere else? Or do I put it in the core somewhere?
