Although Microsoft Internet Explorer lacks support for CSS3, at least until IE 9 debuts later this year, some folks are still working on solving that problem. Developer Jason Johnston has created a utility called CSS3 Pie that lets you use some of the features of CSS3–even in Internet Explorer.
CSS3 Pie is a library that creates DHTML behaviors that IE is able to interpret. It essentially “translates” some CSS decorations, such as border-radius, border-image, box-shadow, multiple background images and gradient backgrounds.
The site is currently just a demonstration that Johnson has created to showcase his work, but it will eventually become a useful utility, if he continues to update it. With IE9’s release looming in the future, he better hurry up.
