iOS Input Focused Inside Fixed Parent Stops Position Update of Fixed Elements

How to stop mobile safari from setting fixed positions to absolute on input focus?

Safari has supported position: fixed since at least version 9.2, but if you're seeing difficult issues, you can fully create the fixed position effect by making the document element and body full screen and then using absolute positioning. Scrolling then occurs in some main container element rather than the body. Your "fixed" elements can exist anywhere in the markup using this method.

jsfiddle here

html,
body,
.mainContainer {
  height: 100%;
  width: 100%;
  overflow: hidden;
  margin: 0;
}

.mainContainer {
  overflow: auto;
}

.fixed {
  position: absolute;
  bottom: 20px;
  left: 20px;
}

position: fixed doesn't work on iPad and iPhone

I ended up using the new jQuery Mobile v1.1: http://jquerymobile.com/blog/2012/04/13/announcing-jquery-mobile-1-1-0/

We now have a solid re-write that provides true fixed toolbars on the
a lot of popular platforms and safely falls back to static toolbar
positioning in other browsers.

The coolest part about this approach is that, unlike JS-based
solutions that impose the unnatural scrolling physics across all
platforms, our scrolling feels 100% native because it is. This means
that scrolling feels right everywhere and works with touch, mousewheel
and keyboard user input. As a bonus, our CSS-based solution is super
lightweight and doesn’t impact compatibility or accessibility.
