Understanding Cascading Style Sheets
Like HTML, CSS capabilities are defined by an evolving set of specifications. The current published
recommendation
is CSS 2.1 and the next version being drafted is referred to as CSS3. However, it has been broken
down into over 50 “modules” with a separate specification for each. As of this writing, only a few of these modules
have become official W3C Recommendations (REC) and several more are at W3C Candidate Recommendation
(CR) status.
At the time of this writing the W3C Recommendations are:
•
Color
•
Namespaces
•
Selectors Level 3
The candidate recommendations are:
•
Backgrounds and Borders
•
Marquee
•
Media Queries
