Snabbit focuses on moving things around. It will translate, rotate, scale, skew and resize your elements. By including matrix multiplication operations, transforms can be combined in any way you want. The end result is then set via CSS3 transform matrices.
snabbt.js is built to be fast. It will only animate things that modern browsers can animate cheaply: transforms and opacity. The goal is to make a library that will let the user make smooth animations without needing to know too much about browser rendering.
