fixed positioning in MobileSafari

Answer 1

I think gmail just tracks the scroll position on a timer and repositions a div accordingly.

The best solution I've seen is at doctyper.

A simpler jQuery solution that moves an element onscroll: link

I found this just now: http://doctyper.com/archives/200808/fixed-positioning-on-mobile-safari/

Answer 3

This fixed position div can be achieved in just 2 lines of code which moves the div on scroll to the bottom of the page.

window.onscroll = function() {
  document.getElementById('fixedDiv').style.top =
     (window.pageYOffset + window.innerHeight - 25) + 'px';
};
