While I'd normally object that classes are purely an author extension
point and UAs should stay out, this is a UA-generated page in the
first place so it's not a big deal.
I might suggest using a pseudoclass instead, though, as that's the
normal UA extension point. Is there any particular reason to prefer a
class over a pseudoclass?
