Prevent Animation jerky in webkit based browsers (Safari and etc.)

gistfile1.css

Webkit flicks if the element you want to animate is bigger than the screen.
The Fix: 
Add these two properties to prevent flickering effects:

-webkit-transform: translateZ(0);
-webkit-perspective: 1000;
-webkit-backface-visibility: hidden;
