It is CSS, there isn't much to debug; especially since they don't have any other site CSS. If you look at the edit history for the CSS page, they created the page while adding the CSS just 1 minute before making their post here. As of this post, they haven't made any other edits to their site CSS so the fact that it is now working supports my hypothesis that it was just a caching issue.
