The CSS Zen Gardener site has been around since about the summer of 2003, but I think it’s an inspiring site for those interested in learning CSS.

The project was created by 25 year old web-design amateur (at the time), David Shea, from Kamloops BC. Participants are encouraged to try their hand at CSS using the HTML content of the site (no content is to be changed). The result is an amazing variety of designs and an excellent demonstration of how powerful and flexible CSS can be.
