Through the library I need to be able to:
-specify which DIV is acting as my bar (there could be more than one, and the DIV can contain children DIVs)
-specify if the bar is docked on the bottom/top/left/right of the screen
-I need to be able to specify padding, width, height, etc
There are several implementations out there, however most of them flicker/shake as the user scrolls. The best implementation I have seen so far is the one in Facebook for the chat/notification bar.
It has to be original code, do not copy. You can look at how others have implemented it, but I want original code which I will have the rights to.
