+ ============================
+ ====== PIE ======
+ ============================
+ Mmmmmm, pie.
+CSS Level 3 brings with it some incredibly powerful styling features. Rounded corners, soft drop shadows, gradient
+fills, and so on. These are the kinds of elements our designer friends love to use because they make for attractive
+sites, but are difficult and time-consuming to implement, involving complex sprite images, extra non-semantic markup,
+large JavaScript libraries, and other lovely hacks.
+CSS3 promises to do away with all that! But as we all know, due to Internet Explorer's lack of support for any of
+these features, we must be patient and refrain from using them, and make do with the same old tedious techniques for
+the foreseeable future.
+Or must we?
+PIE stands for Progressive Internet Explorer. It is an IE attached behavior which, when applied to an element, allows
+IE to recognize and display a number of CSS3 properties. Consider, if you will, the following CSS:
+ #myElement {
+ background: #EEE;
+ padding: 2em;
+ -moz-border-radius: 1em;
+ -webkit-border-radius: 1em;
+ border-radius: 1em;
+ }
+This results in a box with nicely rounded corners in any of today's modern browsers, except of course for IE 6, 7, or 8,
+which all display a square box. However, add the following single rule to that CSS:
+ #myElement {
+ ...
+ behavior: url(;
+ }
+Now the exact same rounded corners appear in IE! That's all there is to it. No, really, I mean it.
+PIE currently has full or partial support for the following CSS3 features:
+ * border-radius
+ * box-shadow
+ * border-image
+The following features are under active development and should be available soon:
+ * multiple backgrounds
+ * multiple box-shadows
+ * linear and radial gradients as background fills
+And after that, who knows, there's plenty of cool stuff we could do!
