Install a utility like Firebug for Firefox and enable it. That will allow you to see every element on the screen and see what bit of CSS it uses. Useful if you want to change the skin in any way. It will also allow you to see any other HTML/CSS/Script stuff you can search for in the various php files that make up Mediawiki.
