I didn't write too much of the css, but I do still take care of it. Not idea how that = instead of : slipped in. Even I'm not normally that bad with css (and emacs syntax highlighting even makes it clear that what was there was wrong). So I fixed that bit.

I agree about the :hover state for accessibility but since that touches the entire site (or at least should) and we already have some :hover stuff on the certain elements it requires a little thought/experimenting (more than I have time for this afternoon anyway).
