Well, last time I checked, the default skin of your wiki was Vector, not Monobook. Things are styled differently on both skins. You should use MediaWiki:Common.css for styles applied to the content of the wiki (the "common" part between skins).

There are no "themes" for MediaWiki (for a particular skins), but instead you can style it with CSS directly. Although that requires you some knowledge about CSS.
