IOS Webkit - native internal scroll - a fix for the document page-bounce
Raw
scrollfix.html
<!DOCTYPE html>
<html>
<!-- NOTES
Demo - uses IOS native scroll available in IOS5, but sidestep the document-bounce behavior.
another take on the solution first seen here: https://gist.github.com/1372229
https://github.com/joelambert/ScrollFix/issues/2
Tested on iPad 2, using IOS 5.0.1.
this solution does not require javascript or setting explicit heights on panels,
but uses flex-box layout for filling up available height.
the classes .vflex and .scrolling are added to the html structure for clarity
We need a wrapper (in this example .master and .detail) which are flex-boxed and given overflow-scrolling:touch.
the same goes for the .panel element.
.panel-content gets margin-bottom:-1px which seems to kill the page bounce for the document.

Just something I noticed about this when I was implementing this solution on my app. If you have display: block; on any of the container divs with the master scrolling divs then it will break the page scrolling. It took me about 3 hours+ to figure that out.
