Smooth and Lightweight ModalBox for Popups

ModalBox is a JavaScript technique for creating modern (Web 2.0-style) modal dialogs or even wizards (sequences of dialogs) without using conventional popups and page reloads. It’s inspired by Mac OS X modal dialogs. ModalBox is built with pure JavaScript and is very lightweight (10kb).

Requirements: Safari, Camino, Firefox 1+ and Internet Explorer 6+, Opera 8+
