I was heartbroken to find that my favorite reference page for CSS combinators was gone this morning. Apparently the entire wordpress site was deleted. So I harvested the data from the google cached page and am posting it here. I'd like to give the author credit but unfortunately I cannot get to the old "about" page, even through various search engine caches. So thanks, whoever you are. :)
"I’m no Zeldman, but I’m pretty good at CSS. I used to do some web development on the side and I made it a point to make all of my sites fully standards compliant and semantic.
