I see. Interesting. It isn't listed on the help page and apparently a few other new ones were recently added as well. Well, I am not actually sure if they are new but they are newly listed.

Based on the description, it seems like you should just be able to use it like any other CSS page. That being said, sometimes it takes time for CSS changes to appear. How long after the changes did you wait before deciding it didn't work? It might also be that these new CSS pages are part of the UCP and are not actually currently in use.
