Discovered yesterday as I was working on some site designs at work. Some very nice sites and some very informative.

• CSS Tabs: Zeldman calls these the best tabs ever. They’re ok. I think the submenu works if you don’t have a lot in level 2. But if you have long titles or a long list, this design breaks down.
• Clagnut: links to some css tutorials and is itself a beautiful site.
• Styling Blockquotes: is one of the better ones Clagnut links to. Don’t be surprised to see this appear on this site in the not-too-distant future
• Plone is a content management system. I think the site has an elegant design that uses excellent CSS.
