Yes, I'd asked Jeff to look into standardizing some basic CSS stuff for OpenACS, in part motivated by the fact that Sloan had slightly forked some code in order to include Sloan-specific CSS stuff for SloanSpace. Forking we and they want to avoid so we do want to regularize this stuff and get back to common sources.
Anyway ... Jeff would be an ideal person for you to talk to if you want your template CSS stuff checked for correctness.
