Ryan Carver has built a site for Lee Jeans and describes how its CSS and XHTML 1.0 Strict are achieved.
The site doesn’t actually look particularly different or groundbreaking, but if you view the normal front page with the stylesheets switched off you can see how much is achieved with CSS. Very impressive, and more so when it’s for a commercial client. He uses a lot of very nasty hacks to get things working on as many browsers as possible, which always makes me uneasy; doing things the “right” way and then hacking in special cases seems plain wrong. But clients aren’t really going to care about the purity of their site’s CSS as long as it looks how they expect. Excellent stuff, and it makes me feel like a CSS amateur.
