Cascading Style Sheets, Level 1: @W3C | The original specification first released in 1996. Covers all the basic properties and simple selectors which work reliably in most modern browsers.
XHTML 1.0: @W3C | The specification for XML which behaves just like HTML in all browsers. Follows a stricter rule set, and thus, is easier to error-check using common HTML validators.
CSS1 Support Chart: @Netscape DevEdge | Eric Meyer’s original chart detailing browser support for CSS1. Becoming rapidly outdated, but still useful for checking available values for CSS1 properties.
XHTML 1.0 Reference Chart: @W3Schools | Indispensable chart of every available XHTML element (listed alphabetically), and which DTDs (Strict, Transitional, and Frameset) allow them. Each element (tag) is clickable to a page defining that element and its possible attributes.
Cascading Style Sheets, level 2 revision 1: @W3C | Revised version of CSS2, originally released in 1998. Adds media types, positioning, overflow and visibility properties, generated content, new pseudo-classes, and a whole new set of powerful selectors. Most of the CSS used on the web today relies heavily on the additions in CSS2.1. However, even the most current browsers still have discrepancies and imperfections, and lack complete support of this specification.
