This is a Prototype conversion of the jQuery plugin scrollFollow. You can find the original script at the following URL http://code.google.com/p/jquery-scroll-follow/ I could not find an existing javascript snippet to set up making a DOM Element scroll with the page that worked using Prototype and script.aculo.us so I ended up converting this jQuery snippet. Most of the functionality has been kept, save for a few things listed below. Current isues: - The original script including optional functionality for user preference to not scroll and binding to a toggle element to turn the scrolling off, I left this functionality out in favor of getting the core working. - The offset parameter doesn't seem to work correctly, and not at all in Opera. - Probably more... Requires Prototype 1.7 (Element.Layout)
