I have a div which, when my page is first loaded, is about 100px from the top (it holds some buttons etc. for the page).

When a user scrolls past it, I would like the div to "follow" the user in that it attaches to the top of the screen. When the user returns to the top of the page, I want it back in its original position.

Visualization - xxxxx is the div:

Default (page load)          User vertically scrolled well past it
---------                    ---------
|       |                    |xxxxxxx| < after div reaches top of screen when
|xxxxxxx|                    |       |   page is scrolled vertically, it stays
|       |                    |       |   there
---------                    ---------
