Thanks again to flex-mx for another great link. I stumbled upon the CSS Zen Garden site quite a while ago. As is talked about in this post, most of the designs aren't too useful. However, you can spend hours clicking through the different CSS layouts and designs that have been submitted by web designers and graphics artists from around the world. It's neat to see how, just using CSS, talented people can completely change the look and feel of the same content. Or maybe it's not neat and I'm just a huge geek with too much time on my hands.
At any rate, it looks like there is now a book that goes through the ins and outs of good CSS design using the CSS Zen Garden samples as examples and illustrations.

The Zen of CSS Design is a book-version of the CSS Zen Garden, and available for pre-order on Amazon according to Mezzoblue. Wonderful idea... always nice to see great designs on paper....
