Many, many moons ago, when CSS was a brand new toy for us developers to play with, I created a quick reference guide for my own use. It made its way into the wild, and many of my colleagues still thank me for creating it. It is long past time that I updated this handy reference.
I only mark support where it is complete, partial, or buggy support does not cut it. If we developers cannot reliably use the feature on that browser, I do not consider it supported. There are a few exceptions, all of which are noted.
Your input is greatly appreciated. Please send your additions and corrections with your source!
