Efficient CSS

It's odd when I can visualize my brain working. I'm going through the morning news in SharpReader and I see there are some new Zeldman posts. One is on writing efficient CSS at CommunityMX. This of course grabs my attention. I like articles like this. As I'm reading through the article I can't help but feel like I've read something on this topic before with a very different slant.

A few google searches later I've tracked it down at Mozilla.org. It was that shady character David Hyatt who wrote about how to write efficient CSS for the Mozilla parsing engine.

One is about cutting down on the file size of your CSS and the other is about how not to make the Moz CSS render engine work hard. I would say those are two very different takes on "efficient CSS," but both are well worth reading. I'm not sure how relevant the Moz optimizations are to how other browsers parse CSS, but they look like good ideas.
