CSS Cookbook, 2nd Edition by Christopher Schmitt (O’Reilly 2006) is part of O’Reilly’s series of reference books falling into the cookbook category. The books use an organization scheme that is good for finding answers to specific questions quickly, rather than reading cover to cover. It’s reference shelf material, not textbook material.
Other problems are solved in just a couple of pages, for example, "You want to make it difficult for people to copy your images from your web page," is covered in two pages with a suggestion to use a background image behind a transparent GIF and a warning that people will still steal the image anyway if they are determined.
In teaching terms, any O’Reilly cookbook is good to have handy, especially for the times when students are designing their own projects and come up with some new twist that hasn’t been addressed in class. As you might expect from a reference book, the appendices are thorough and helpful.
