Query: This is the old edition. It was a 5-star book 4 years ago.

Eric Meyer is the master. This edition is way out of date. Instead, buy Cascading Style Sheets: The Definitive Guide, 2nd Edition. It explains everything about CSS2 in detail. For examples and workflow, buy Eric Meyer on CSS and More Eric Meyer on CSS. Just don't buy this outdated version of The Definitive Guide.
