One of the most keenly-anticipated CSS3 properties is border-radius. Web designers will no longer have to resort to complex table structures using custom-made corner graphics or including arcane JavaScript files in order to produce designs with rounded corners.

While Internet Explorer doesn't support many (or any) advanced CSS properties, you can get started using Firefox and any of the 'Mozilla' family of browsers. Apple's WebKit web browser engine also supports rounded corners making them available in the Safari and Chrome web browsers, the iPhone and other devices running WebKit.
