Copy-paste this into library/Application Support/Google/Chrome/Default/User StyleSheets/Custom.css. I think you can probably have more than css files in there, but I haven't tried it out.

Library's hidden by default, but if you click on the "Go" menu in Finder, than hold down the option key, Library will appear.
