I like Robin Nixon crash courses as he goes straight to the point, writing in a few pages what other books explain ad nauseum in hundreds of pages. The way Robert explains the selectors is absolutely genius, in 5 pages I got it all. It also explains the new CSS3 techniques, how you make a beautiful rounded box, write in columns, position boxes a.s.o. There is no specific example code of a beautiful website however. As an introductory course, definitively worth buying!
This is just what it says...a crash course. Well, brief introduction would be a better title as it skips through the subject giving the reader an overview. If you're just curious about CSS/CSS3 then this will give you an insight. If you're looking for a book to help you design your site...you will need something a lot more comprehensive than this. I already knew enough to use CSS3 from previous experience and site design...I would not have been able to do anything from the contents of this book.
