Difference between CSS2 and CSS3

The biggest difference between CSS2 and CSS3 is that CSS3 has been split up into different sections, called modules. Each of these modules is making it is way through the W3C schools  in various stages of the recommendation process. CSS2 was submitted as a single document with all the Cascading Style Sheets information within it. Because each of the modules is being worked on individually, we have a much wider range of browser support for CSS3 modules.A superset of CSS,  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. CSS3 is the latest standard  version for CSS. Though CSS3 is not fully supported yet, many web developers are starting to use many of the new techniques introduced. Some of the CSS3 features are-

1. Border Radius
