Css rounded corners without images

I found a neat summary on Jon Raasch’s blog of a technique for producing rounded corners in IE using a behaviour htc file.

I’d previously been trying out this jquery corner plugin which works well enough but I think Jon’s suggestion is cleaner and allows Firefox, Chrome and Safari to achieve the effect completely natively with no javascript. Some care is needed with inline elements as Jon points out but other than that it’s a quick and effective solution that works well for me.
