If you wish to see the power of CSS in action, visit CSS Zen Garden. Here you can see how different designers responded when asked to use the same HTML document but develop their own CSS document. When the last submission was accepted in 2007, there were 213 official designs— that’s 213 different designs for one HTML document.
I was fortunate enough to have my submission accepted and added to the official list.
