Admin Forum:CSS for individual pages outside of main namespace

I've been trying for over an hour to define a CSS style for a page outside the main namespace. But I can't quite figure out the nomenclature. For instance, I'm trying to change the pre style of only MediaWiki:Wikia.css. The basic form for page styling is well understood: body.page-whatever element { style } This will successfully apply sstyle to the element on the page called whatever only.

But I can't seem to figure out how to successfully refer to Wikia.css. I've tried: body.page-MediaWiki:Wikia.css body.page-Wikia.css body.page-NS-8:Wikia.css body.page-ns-8:Wikia.css body.page-ns_8:wikia.css ... and lot of other varitions in between None of it seems to work. Anybody got any cues on the right way to refer to a MediaWiki (or any other non-main namespace) page? 04:06: Thu 17 May 2012
 * Never mind. Figured it out.  It's all underscores.  So .page-MediaWiki_Wikia_css  04:24: Thu 17 May 2012
