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. And yes, it may also be useful for showing larger versions of images. 
ModalBox is built with pure JavaScript and is based on Sam Stephenson’s excellent Prototype JavaScript Framework, script.aculo.us and valid XHTML/CSS. ModalBox uses AJAX to load content.
That’s the blurb and I have to agree with it. Modalbox is nothing short of stunning. In 10 minutes I was ‘mashing it up’ with SPRY Datasets, creating a really amazing way to display a Database. I’ll be releasing the ‘Mash-Up’ later this week, so stay tuned.
It’s very easy to customize and works in all popular browsers. It runs better in FF, IE is a lot more fussy about usage. You could use this for countless things, Log In Boxes and Site Tours seem the most obvious followed by a Contact Form.
