title: Why are some websites not zoomable on iPad?
body: <p>Does anybody have any idea why iPad zoom (you know, where you use two fingers to enlarge the text/screen) does not work on some sites?</p>
  
  <p>For example:</p>
  
  <ul>
  <li>facebook.com</li>
  <li>c3.arc.nasa.gov/nex/ ± the site that I'm working on.</li>
  </ul>
  
  <p>Google search does not reveal anything, which makes me think it’s not a common problem.</p>
  
  <p>Thanks beforehand for any insights.</p>
