How would you do this with a CMS? How to do with dynamic content when serving the CSS from a cookieless, static domain as it's best practice for performance.
From my point of view it can't work with just CSS. When you look to my proposed gist-solution you can see in history that I've already dealt with several other approaches.
Last is the only one that could really work that I know right now.
