A.2.1. Style Sheets Reference Guide (SSRG)

http://www.webreview.com/style/index.shtml

This site is home of the Browser Compatibility Charts, which is its main claim to fame. The Chart is a listing of every property and value in CSS1 and the status of its support in each of several major browsers, with notes explaining the ratings. As of this writing, the Chart covered 10 major browser versions, with more expected, and there were plans afoot to add CSS2 support tracking to the charts as well.

The SSRG is also the home of the Web Review column "A Sense of Style," with archives of all the articles, and sections devoted to CSS question and answers, common mistakes with CSS, cool ways to use styles, and more. (Disclaimer: the SSRG is edited and maintained by the author of this book.)

A.2.2. CSS Pointers Group (CPG)

Maintained by CSS gurus Sue Sims and Jan Roland Eriksson, the CPG is a wonderful collection of articles, bug reports, workarounds, and literally hundreds of other resources. Many of the pointers listed are simply links to material generated by various people throughout the Web, but some of the best articles are the work of Sue and Roland themselves. The site can be a little difficult to navigate at first, but the enormous wealth of information available through these pages makes the effort well worth it.

A.2.3. WSP CSS Samurai Reports

http://www.webstandards.org/css/

A series of documents detailing the major failings in CSS support in available web browsers, written by the CSS Action Committee -- or, as they are sometimes called, the "CSS Samurai" -- of the Web Standards Project (WSP). As of this writing, there were reports covering Internet Explorer for both Windows and Macintosh, and Opera for Windows. These reports offer an interesting insight into what can go wrong in browser support, what designers want to see, and how to test for CSS support problems.
