title: Adjusting browser zoom level with Javascript
body: <p>In the 2-frame 'rows=' frameset I have, if a user change of the zoom level to less than the 125% value that I coded for, they will see "dead space" between the frames.</p>
  
  <p>This question: <a href="https://stackoverflow.com/questions/1713771/how-to-detect-page-zoom-level-in-all-modern-browsers">How to detect page zoom level in all modern browsers?</a> shows how to detect the browser's zoom level. </p>
  
  <p>Is it possible to adjust the browser's zoom level using Javascript so I can keep users from changing the zoom outside of the desired levels?</p>
  
  <p>Or have I simply forgotten a default coding consideration of some kind? (I've seen CSS's 'zoom' style, where presumably default zoom levels can be set.)</p>
  
  <p>I am also seeing <code>document.body.style.zoom</code>, so seems we could do something like:</p>
  
  <pre><code>if (zoomLevelChange)
    {document.body.style.zoom= [some calculation]; }
  </code></pre>
