Yeah, it’s true—you can actually make functional drop-down menus with CSS. The link contains a very interesting article.
By the way, A List Apart seems to be a pretty good source to learn little hints and secrets about CSS.

The site design is pretty decent, too. Nice coding, good layout.

We were going to do a CSS drop-down menu for the new Brainfuel site, but we could never resolve the Win Internet Explorer problem. We got it to work with the php include categories thing, though, so that was cool.

I figured out a cute little trick for designing templates while working on Brainfuel: Experiment on a blog elsewhere on the server, but using the same MySQL database. It worked for me, and was a good simulation of actually editing the real BrainFuel, without actually doing so.
