When it arrives later this year, Internet Explorer 9 will support most of the latest decorations and behaviors in CSS3. But until then, you’re stuck with the same old workarounds for IE users.
Here’s something that might make your life as a designer a little bit easier: CSS3 Pie is a new library written by Jason Johnston that lets you use several of the latest CSS3 enhancements and still have them show up in Internet Explorer versions 6 through 8.
It creates DHTML behaviors that IE can understand, and then it controls how they’re presented. The library can be used to translate a few CSS decorations:
box-shadow, multiple background images and gradient backgrounds.
Right now, it’s just a demo, and since it uses .htc files for DHTML behaviors, it causes a serious performance hit on some versions of IE. It will likely become more useful in the future as Johnston builds it out. Follow Pie’s progress on Twitter.
Is it a good idea? On one hand, it’s just another life support mechanism for IE6. But it also gives us an easy enough fix where we can continue creating modern designs without having to worry as much about alienating those visitors stuck using browsers that don’t have proper CSS3 support.
Also, A List Apart recently ran an excellent tutorial on using Modernizr to smooth the transition to HTML5 and CSS3.
