PIE (Progressive Internet Explorer) is an IE attached behavior that allows IE 6-8 to recognize and display a number of CSS3 properties. It currently has full or partial support for the following CSS3 features: border-radius, box-shadow, border-image, multiple background images, and linear-gradient as background image.

Using PIE in your projects is really simple and straight forward. All you need to do is upload “htc” file on the server and add the behavior in CSS rule of the element: “behavior: url(path/to/PIE.htc);”. You need to make sure that path is relative to the HTML file being viewed, not the CSS file it is called from.

Hi,
I’ve seen lots of buzz about PIE and if it lives up to the promise, then Hallelujah! Has anyone tried it in the wild and with what level of success?
Cheers,

I tried it and it works with ugly bugs and sites got really really slow, still I think an amazing solution
When you browse to the PIE website in IE8, you can see the drop shadow and rounded corner effects at work. But for me, operations like scrolling the page seem to be jerky and slow. Obviously the browser is doing a lot of processing behind the scenes. The CSS3 effects might be nice, but if it slows down page response too much, you would have to ask, is it worth it?
