Velocity is an animation engine with the same API as jQuery's `$.animate()`. It works with and without jQuery. It's incredibly fast, and it features color animation, transforms, loops, easings, SVG support, and scrolling. It is the best of jQuery and CSS transitions combined.

Download Velocity, include it on your page, and replace all instances of jQuery's `$.animate()` with `$.velocity()`. You will immediately see a performance boost across all browsers and devices — especially on mobile.

Velocity works everywhere — back to IE8 and Android 2.3. Under the hood, it mimics jQuery's `$.queue()`, and thus interoperates seamlessly with jQuery's `$.animate()`, `$.fade()`, and `$.delay()`. Since Velocity's syntax is identical to `$.animate()`, your code doesn't need to change.

Velocity outperforms jQuery at all levels of stress, and outperforms Transit (the leading CSS animation library) beginning at medium levels of stress. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow.
