This month while involved on the redesign of a very popular website I decided not to use HTML tables anymore - or at least avoid its use as much as possible. Ten years ago - when I started building websites - Tables were your friends not your foe. Along came CSS and the idea of separating the content from the way it is presented.
 
CSS is been around for a while and almost all the sites currently use it somehow but do they use it well? Check out CSS Zen Garden and decide if your site allows being re-skinned as much as this site.

It’s been an excellent experience and I’ll be posting some tips about how to build CSS-friendly sites in the future.
