The indespensible sequel to his first book, this one serves as an advanced tutorial teaching you complex CSS such as CSS-Positioning by using real-world examples that you will surely face in the not-to0-distant future. Learn how to make CSS-driven drop-down menus, completely table-free web design layouts and more, all while looking over Eric’s shoulder as he shows you what to do! Also a great reference book for tips and tricks to avoid common pitfalls.

Still working my way through some of the exercises. Also useful as a reference, I find I keep coming back to it.
