title: Want an iPhone / iPad / iOS Webpage that is 100% width/height
body: <p>I'm trying to get a site that is simply 100% of the possible width/height of a device, after scrolling down far enough to get rid of the address bar.  Hopefully that makes sense?</p>
  
  <p>I just need the simple dimensions so I can scroll the device to 0,0 and see as much of my page as possible.  e.g. simply 320x400 (320 width, 400 might = height - title bar - footer)</p>
  
  <p>The reason for this is that I'm putting a single DIV on a page that is a "viewport" into content that moves around, think google maps.  I just want this div to fill all available space.</p>
  
  <p>The problem is that I can't seem to detect the available window height.  I always seem to get the screen size - the title bar - the address bar - optional debug bar - footer.  How do I detect the "largest possible size"?</p>
