Two of the most celebrated enhancements to Safari on iOS 5 are fixed positioning and content scrolling support. This tutorial will teach you how to take advantage of this change and what the implications are for stop-gap JavaScript libraries like iScroll.

In a previous tutorial, I talked about iScroll and how this great little plugin helped fix an issue with iOS Webkit (5.0 and below) and Android Webkit (2.1 or below), in which there was no native support for fixed positioning or scrollable content areas.

So, after a weekend of running various tests, it's nice to confirm that the iOS 5 Safari update now tackles both of these issues and we now have full native support for them. It has been in the pipeline for some time in terms of the beta releases for iOS 5, but you can never guarantee that these things will make it to the final release.

In this tutorial, I will discuss this change at length and also teach you how to convert the iScroll project from our previous tutorial to using the new CSS properties.
