Create a floating Region that is pinned in place while you scroll screen

OK I came across an easy trick to make a region "float" in the same place on the screen while the rest of the page scroll. Very useful for having some basic reference information (invoice header) always available as the user scrolls through a long transaction log.
Here's the steps:
  1. Make the region (perhaps a sidebar region
  2. Display the page in APEX and View Source in the browser
  3. Find the first item in that region using the CTRL F find
  4. Identify the parent class to the Region Header.(Mine was t15RegionHeader and the parent is t15RightBar)
  5. Paste this code into the Region Header in the APEX Region definition form

This makes the region float on the right since it's a sidebar region in my case.
