I'm looking to re-create the Apple Store shopping cart sidebar.

http://store.apple.com/us/configure/MB535LL/A?mco=MTA4MTg3NTQ

It is similar to "position: fixed" except that it starts out as "position: absolute" with the CSS class "pinned_top" and then switches to CSS class "floating" when a certain scroll-y position is reached.

I've looked EVERYWHERE for this, it seems a tutorial should be obvious but I'm yet to find anything. Any help?
