Cascading Style Sheets (CSS) began as a clean way to separate formatting from content, but it has grown into a powerful toolkit for layout and interface design. CSS Level 3, commonly called CSS3, divides its work up into modules, many of which are available for you to use today. What's New in CSS3 provides a brief overview of the many parts of CSS3 whether they are Recommendations, Working Drafts, or pieces left aside. Transformations and Animations may be highly visible parts of new interface styles, but new selectors and layout approaches will also change the way you work. If you've been wondering which parts of the CSS3 conversation are for you, What's New in CSS3 will get you started.
