Hi, I have managed to work out how to use HTML and CSS thanks to the Sitepoint book and made a website - http://www.ubereadoolische.com/.

However, how would I go about learning how to create something slightly more modern looking - like http://csszengarden.com/?cssfile=/208/208.css&page=0 for example?

I am a rather confused beginner as to how I go about extending my CSS knowledge.
