Now this is my kind of book, a well stocked reference without all the fluff that usually comes with the explaination of each new idea or concept. You know the sort, a book that you can refer to again and again after learning the basics because it is well organised and laid out. Of course, the reference only style of Cascading Style Sheets 2.0: Programmer's Reference is not really suited to those that are completely new to the topic. Having said that, those familiar with the idea of style sheets might be able to put something together if they mix and match the numerous examples.
Unfortunately there are very few illustrations or screen shots to help you grasp difficult ideas, which sometimes results in long and wordy descriptions of the various properties. I found myself skimming over such busy paragraphs because I knew the idea they were trying to describe, but anyone unfamiliar with the ideas may find themselves getting frustrated trying to work out exactly what it is that is being said. A few more well placed illustrations would have made it easier to use.
Another thing that annoyed me was the repetition of paragraphs while detailing the properties. While I can understand the need to repeat the paragraphs (after all, it is a reference book!), it did get rather tired, particularly when looking up related properties or attributes.
Despite these little annoyances, it makes an ideal quick reference book. The headings and text are clear, the pages easy to scan and alphabetical ordering makes it easy to find attributes by name. There is no obvious distinction between CSS1 and CSS2, but important differences in implementation of the two are pointed out when relevant.
