title: How to disable page scroll when keyboard pops up
body: <p>I have a web site with an input field.</p>
  
  <p>When the input field is focused, the iPad keyboard shows up and the page scrolls up automatically.  When the keyboard is dismissed, there's no scrolling back to the original position.</p>
  
  <p>Is it possible to programatically disable this behavior (the scrolling) using javascript and/or css ? </p>
