JQuery Transit - CSS3 animations for jQuery
alternatively you can use jQuery Animate Enhanced plugin.
<a href="https://github.com/benbarnett/jQuery-Animate-Enhanced/" rel="nofollow">https://github.com/benbarnett/jQuery-Animate-Enhanced/</a><p>it enhances jquery's own animate function making animations use CSS3 hardware accelerated equivalents in browsers that support them while using the original jquery software mode when not supported. and you don't need to change a single line of code on your site since its completely transparent.
