jQuery Transit - CSS3 animations for jQuery. What about older browsers?
Transit degrades older browsers by simply not doing the transformations (rotate, scale, etc) while still doing standard CSS (opacity, marginLeft, etc) without any animation. Delays and durations will be ignored. // Delegate .transition() calls to .animate()// if the browser can't do CSS transitions.if (! $.support.transition) $.fn.transition = $.fn.animate;
