Forum:Quartz skin syntax for changing wide logo?

I have a wide logo that is loaded as Wiki_wide.png and looks ok with light value backgrounds but looks unprofessional on the dark backgrounds. How do I override in my quartz css? BTW- what are the names of the css's? Mediawiki:Quartzslate.css works, but changing Quartzsapphire.css and so on for the other quartz variants does not appear to have any affect. ~  Ph l o x  23:27, 30 November 2007 (UTC)
 * It's MediaWiki:Common.css. If you want to have your own you need to edit User:Phlox/Common.css (I'm not 100% sure of it), but you need to do that on each wikia you visit. From what I know there is no way to simply change wikia logo by editing one css file, which would appy for all wikias. If you need some stuff - check my Knowledge library - it's not big yet, but am expanding it so soon it will be quite useful thing ;) SkywalkerPL 08:41, 2 December 2007 (UTC)
