title: Set viewport to match physical pixels
body: <p>I'm trying to make the viewport exactly match the physical pixels on the screen.</p>
  
  <p>The page I'm working on's HTML (which I can't change, because that would break other things using the same HTML) includes:</p>
  
  <pre><code>&lt;meta name=viewport content="width=device-width, initial-scale=1"&gt;
  </code></pre>
  
  <p>How would I make the viewport match physical pixels in javascript?</p>
