Lighter.js is a free syntax highlighting class developed with MooTools. It was created with the MooTools developer in mind and takes advantage of many of the Framework’s features. Using it can be as simple as adding a single script to your web page, selecting the elements you wish to highlight, and Lighter.js takes care of the rest.

All browsers supported by MooTools are compatible with Lighter.js. It’s possible that it may work with earlier/other browsers but these are unofficially supported. The official list is:

• Safari 2+
• Internet Explorer 6+
• Firefox 2+
• Opera 9+
