No one book—not even this one—can answer all of your CSS questions. Luckily, CSS resources abound for both beginning and expert web designers. In this appendix, you’ll find resources to help you with general CSS concepts as well as specific CSS tasks, like building a navigation bar or laying out a web page.
References that cover CSS properties range from the official to the obscure. There are websites and online tutorials, of course, but you don’t have to be on the Web to learn about CSS. Some of these guides come on good old-fashioned paper.
CSS Current Work (www.w3.org/Style/CSS/current-work). Here you’ll find all of the CSS specifications, including the newest additions to CSS. The different specifications are organized by status, like Completed, Testing, Refining, Revising, or Abandoned. You can click any specification to dig into the nitty-gritty details, but just because a specification is listed as “Completed” doesn’t necessarily mean it’s been fully implemented in all web browsers. However, this site does provide the final (sometimes overly complex and hard-to-understand) word on CSS.
