I don't really know which book the other reviews are talking about, but I do not have much good to say about this book. Couple of reasons: it's incredibly talkative without actually providing any valuable information above very basic knowledge and tips'n'tricks. For example, although shooting at "designers who understand CSS at an intermediate to advanced level", it spends about five pages on (re-)introducing the box model (you know, what exactly padding and margin refer to). The pace of the book is just painstakingly slow: in the chapter where a three-column layout is introduced, it literally builds the three-column layout from a simple text page up, depicting over and over again how the simplest code change affects the browser rendering - only to stop at a stripped-down three-column layout that has achieved nothing (and where you can find much better examples by just typing "three-column layout CSS" into Google).
Now you may say: that sounds great for beginners. It's not at all - since the book doesn't really follow any logic, it just introduces random websites (e.g., fastcompany.com) and uses these websites as an example on how to layout with CSS (then again, without really showing how for example fastcompany.com does it in practice). So there's absolutely no learning curriculum that is being followed.
And lastly, here's my favorite quote: A chapter talking about how to design round boxes with CSS is kicked off by "We also touch upon issues these solutions have with Internet Explorer and provide workarounds (if possible) for this troublesome browser." Yeah guys, too bad that 90% of the world IS using IE. I don't like it either, but it's not my choice, so please give me something I and 90% of the world can work with, and not some geek's elaboration on how great Firefox can render CSS. The chapter goes on to dwell for pages and pages about how to do it, only to conclude that the solution basically doesn't work for IE.
Conclusion: I can't really see who should buy this book - not interesting as a tutorial on CSS (since it doesn't follow any logic and introduces topics as it hums along), not interesting as a resource on coding how-tos (since it's way to shallow on real coding content - see three-column layout), not interesting as a study on how real websites are built based on CSS (because in the end it doesn't really disect these websites or the design choices made, they seem to be used only as an alibi to get on certain topics).
