Thread:Project:Support desk/Some CSS not working?

MediaWiki 1.16.0 PHP 	5.2.15 (cgi-fcgi) MySQL 	5.1.53-log

I'm currently in the process of moving my wikia content over to an install of mediawiki that I just got set up. First thing I did was upload all of my templates and I'm having a bit of trouble getting the formatting of the infoboxes properly.

This is the code in the template:

And this is the code that I added to MediaWiki:Common.css

/* CSS placed here will be applied to all skins */

.infobox { background-color: #DFDFDF; border: 1px solid #D9D9D9; clear: right; color: #3A3A3A; float: right; margin-bottom: 0.5em; margin-left: 1em; padding: 0.2em; }

.color1 { background-color: #1B5775; color: white; }

.color1 renders just fine. However, .infobox doesn't seem to be working and I'm not sure what I'm doing wrong. I'm using the default Monobook skin with no edits.
