#Watch Plugin

This plugin lets you listen for when a CSS property, or properties, changes on element. It utilizes Mutation Observers or the DOMAttrModified / propertychange events, when available, and fallsback to polling utilizing setInterval().

There is both a jQuery-specific plugin as well as a library agnostic version of this plugin available.
