In Firebug it's really easy: Install it, go to your website, press F12. In the menu, which opens then, in the top row the second icon is a rectangle with blue border. Its hover text says something like "Click an element on the page to inspect it." Click the icon and then in the page click the searchbox. Firebug will automatically show you the expanded HTML code and the CSS rules with their cascade at the right side.

You say you had problems sorting the elements in the sidebar. In that context - speaking about CSS problems - I guess you did that with CSS as well? I nearly don't dare telling you, but you know that you can sort them using the wiki page MediaWiki:Sidebar?
