[Help] CSS Value For System Tray Icons

[Joomla12]

Hey guys. I really hate joining just to ask a simple question, but where in the "cinnamon.css" file is the value for system tray icon size? I'm trying to tweak a theme to where the icons actually fit better on the panel (they're currently way too big and sometimes overlap the panel). I've been Googling around for some sort of documentation, but haven't been able to find a thing.
