BTW, you can set diffenent personal CSS for each wiki you edit on. You can set your CSS for the particular wiki on Special:MyPage/common.css instead of manual changing of your global CSS for all wikis on w:Special:MyPage/global.css everytime you change the wiki.

See Help:JavaScript and CSS Cheatsheet for more info.
