fixed layout of CSS keyframes

Hey Zach, I think I messed up on the layout of the keyframes. I had it all wrong!

base on example 4.1, it's actually the last that doesn't have an animation! I'm so sorry! I went ahead and fixed it and added more options to be display on the keyframes such as moz and the normal animation. Also, it works splendidly now. Play around with the knobs, you can go negative and it will follow the curve...it's so cool, check it out!
