Recommended Posts

CSS 1The first CSS specification to become an official W3C Recommendation is CSS level 1, published in December 1996.[3] Among its capabilities are support for: * Font properties such as typeface and emphasis * Color of text, backgrounds, and other elements * Text attributes such as spacing between words, letters, and lines of text * Alignment of text, images, tables and other elements * Margin, border, padding, and positioning for most elements * Unique identification and generic classification of groups of attributesThe W3C maintains the CSS1 RecommendationCSS 2CSS level 2 was developed by the W3C and published as a Recommendation in May 1998. A superset of CSS1, CSS2 includes a number of new capabilities like absolute, relative, and fixed positioning of elements, the concept of media types, support for aural style sheets and bidirectional text, and new font properties such as shadows. The W3C maintains the CSS2 Recommendation.CSS level 2 revision 1 or CSS 2.1 fixes errors in CSS2, removes poorly-supported features and adds already-implemented browser extensions to the specification. While it was a Candidate Recommendation for several months, on 15 June 2005 it was reverted to a working draft for further review. It was returned to Candidate Recommendation status on 19 July 2007.
