If you're looking for quick information in a size that's easy to carry around, purchase this book. It's an excellent addition to the O'Reilly Pocket Reference series.

When I'm trying to remember the format for a particular style or how well it's supported by the various browser versions, I don't want to have to dig through a large reference manual. Instead, I reach for this book, quickly look up the style (listed alphabetically), get the information I'm looking for, and continue working. This is the reference I carry between work and home.

The book starts with a condensed description of how CSS1 works and how to use it. The majority of the reference describes the CSS1 properties, pseudo-elements, and pseudo-classes. Each entry includes the allowed values, a description, a few examples, and browser support for both Windows and Mac browsers. Additional notes describe any browser-specific issues. A browser support summary chart completes the book.

Even if you have Eric Meyer's Cascading Style Sheets, The Definitive Guide, you will still find his CSS Pocket Reference a useful addition to your bookshelf.
