The CSS Vault. One of the two sites (Gadgetopia also) I visit daily. The only source for inspiration. Seriously, if you want to be an excellent web designer (I do!!), you have to use css. Its the new Black!

I needed a site that linked to all the great CSS resources out there on the web. I couldn't find a site that combined those two elements, so I created one myself.

Excellent Stuff. The Archives are Huge.
