Cross-browser gradient backgrounds without images

Summary

This experiment allows for gradient backgrounds on elements by defining a six character hex value for the start and end color as part of the class attribute. No background-images are required. This has been tested and verified to work in MSIE6, Firefox 1.0.7, Safari 2.0.1, Opera 7.5 & 8.5 on Windows 2K, XP and OS X.
