Safari supports CSS3 Background Properties

(via Shaun Inman): Dave Hyatt posts that the Safari web browser supports multiple background images as specified in the CSS3 spec.

That means that you can change your CSS to attach multiple background images to a single element, one of the most desired things imaginable in the world of CSS. Presumably, there will be a way to write CSS to achieve the effect in Safari, while not breaking rendering in browers that don’t support it yet.

Rounded box corners will be a breeze!
