Dynamics.js

Dynamics.js is a JavaScript library to create physics-based animations. You can animate CSS properties of any DOM element. You also can animate SVG properties. And any JavaScript object. Dynamics.js has its own setTimeout. The reason is that requestAnimationFrame and setTimeout have different behaviors. In most browsers, requestAnimationFrame will not run in a background tab while setTimeout will. This can cause a lot of problems while using setTimeout along your animations. I suggest you use Dynamics's setTimeout and clearTimeout to handle these scenarios. Toggle a debug mode to slow down every animations and timeouts. This is useful for development mode to tweak your animation. This can be activated using Shift-Control-D in the browser.
