title: Allow zooming within iFrame but not on page in iOS
body: <p>I have a simple page with</p>
  
  <pre><code>&lt;meta name="viewport" id="extViewportMeta" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no"&gt;
  </code></pre>
  
  <p>on it, with everything sized nicely to display on an iPhone.</p>
  
  <p>But when I put an iframe on that page, everything inside the iFrame is not zoomable, and scales to the size of the parent page.</p>
  
  <p>How can I allow zooming within the iframe only, without messing with the rest of my page?</p>
