Dan Cederholm

Great little book. The writing is clear, the examples are excellent, and the author has an amusing sense of humor. Very helpful. Also points to external (web) resources. I read the first 5 chapters, which is most of the book.

A really good technical book. A surprisingly easy read. I need a refresher on css/semantic design every so often.

I was either unaware or had forgotten that 'kbd', 'var', 'samp' are all valid xhtml tags.

It's like the web was designed to be a technical knowledge base...

This is a great book if you're migrating from classic HTML to XHTML/CSS, as Cederholm shows you how to do a lot of nifty tricks with CSS and tableless design. If you're still using FONT tags and spacer shims, you really need to pick up this book. Even if you're already using XHTML/CSS, I recommend you pick up this book as it can really help you solidify your designs.

Excellent if you want to get up to speed quick on a few of the CSS design methodologies used.

It certainly isn’t exhaustive, but Dan covers the popular concepts in detail comparing a non-bulletproof approach with a new CSS bulletproof approach.

Anyone working in the UI should read this book if they haven't already.
