Whilst reading Steve Krug’s excellent “Don't Make Me Think!: A Common Sense Approach to Web Usability” I came across a wonderfully simple and evocative web site – CSS Zen Garden.
I’m a developer and engineer, not a designer, so elegant, well designed web sites always impress me, because I know I could never achieve such beauty. This site has a selection of superb CSS style sheets that you can click on to dramatically change the look and fee of the site, but one only using CSS – the HTML stays the same. If you doubt (or just plain don’t understand, like me) the power of CSS, spend a few minutes on the site.
