This brief slideshow gives you an idea of what css3 is capable of.

1. The Basics of CSS3

2. Brief Intro
CSS (Cascading Style Sheets) have been around for awhile now
which allow us to produce better websites. Due to the
advancement of CSS3, we are now able to do things a lot easier.
Things such as drop shadows, rounded corners, text
shadows, multiple background images, and much more. Although
the capabilities of CSS3 have expanded, most of the
customizations will only be noticed in Google Chrome, Firefox, and
Safari.

3. Rounded Corners
Example of Code:
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
