it fixes the issue You should be able to set the CSS3 Transform property using JavaScript to scale content. This won't be tied to the web browser zoom functionality though.

I wish this help you The following works in Safari 4.0.2 and latest WebKit nightly. It doesn't work in Google Chrome (neither Windows nor Mac), however.
As for Firefox 3.5 and IE 8.0, no deal. Also, no deal on latest Camino nightly.
code :
<style type="text/css" media="screen">
  iframe {
    width  : 500px;
    height : 250px;
  }
</style>

<script type="text/javascript" charset="utf-8">
  function setZoom(element, zoom) {
    element.style.zoom = (zoom || 50) + '%'
  }
</script>

<p>Hello World</p>

<iframe 
  src    = 'http://google.com' 
  onload = "setZoom(this.contentDocument.body)"
  />

To fix the issue you can do Now it's an even bigger mess than it was when this question was first asked. From reading all the responses and blog posts I could find, here's a summary. I also set up this page to test all these methods of measuring the zoom level.
Edit (2011-12-12): I've added a project that can be cloned: https://github.com/tombigel/detect-zoom
code :
<style id=binarysearch></style>
<div id=dummyElement>Dummy element to test media queries.</div>
<script>
var mediaQueryMatches = function(property, r) {
  var style = document.getElementById('binarysearch');
  var dummyElement = document.getElementById('dummyElement');
  style.sheet.insertRule('@media (' + property + ':' + r +
                         ') {#dummyElement ' +
                         '{text-decoration: underline} }', 0);
  var matched = getComputedStyle(dummyElement, null).textDecoration
      == 'underline';
  style.sheet.deleteRule(0);
  return matched;
};
var mediaQueryBinarySearch = function(
    property, unit, a, b, maxIter, epsilon) {
  var mid = (a + b)/2;
  if (maxIter == 0 || b - a < epsilon) return mid;
  if (mediaQueryMatches(property, mid + unit)) {
    return mediaQueryBinarySearch(
        property, unit, mid, b, maxIter-1, epsilon);
  } else {
    return mediaQueryBinarySearch(
        property, unit, a, mid, maxIter-1, epsilon);
  }
};
var mozDevicePixelRatio = mediaQueryBinarySearch(
    'min--moz-device-pixel-ratio', '', a, b, maxIter, epsilon);
var ff35DevicePixelRatio = screen.width / mediaQueryBinarySearch(
    'min-device-width', 'px', 0, 6000, 25, .0001);
</script>

it should still fix some issue Apply an AlphaAnimation to the widget, going from an alpha of 1.0 (opaque) to 0.0 (transparent). Start the animation whenever you want it to fade out. Set up an AnimationListener on the AlphaAnimation to call setVisibility(View.GONE) on the widget when the animation ends. When you want the widget to re-appear, call setVisibility(View.VISIBLE).
