title: Different viewport widths for landscape and portrait
body: <p>My website is more or less optimized for mobile devices, however it needs a minimum width of 480 px.
  Using</p>
  
  <pre><code>&lt;meta name="viewport" content="width=480"&gt;
  </code></pre>
  
  <p>works well, but only in portrait mode. If I switch to landscape, it uses 480 px too, which makes everything too big.
  Is there a way with maybe a script to switch to a higher width if landscape (mobile users only) is used?
  Thank you.</p>
