Cody Lindley wanted to do more with the lightbox technique, so he created ThickBox. “My version of the Lightbox technique includes functionality similar to that of the Greybox technique. That is, ThickBox can show html pages as well as images. The html that is shown inside ThickBox is pulled from the server using AJAX (really AXAH). I would like to think that my twist is bridging the gap between Greybox and Lightbox functionality.
