A css discussion...

[Eli Cochran]

This reminds me of code that I've written in the past which  
dynamically adds a class "last" or "first" to an element because IE  
doesn't support the first-child and last-child pseudo selectors. And  
then, of course, my CSS had to include redundancies:
foo.first, foo:first-child {}

I think that I read somewhere that one or more of the browsers are  
supporting ARIA attributes as CSS selectors. But maybe I just dreamed  
it. (Don't have time at the moment to look it up.)
