title: Why is 'projection' an invalid value for the media attribute in a link tag?
body: <p>According to the <a href="http://validator.w3.org" rel="nofollow noreferrer">w3.org validator</a>:</p>
  <pre><code>&lt;link rel=&quot;stylesheet&quot; href=&quot;css/style.css&quot; media=&quot;screen, projection, tv&quot; /&gt;   
  </code></pre>
  <p>does not seem to be valid anymore due to the <code>projection</code> value.</p>
  <p>I don't remember exactly, but this way Opera in Fullscreen is included.
  Probably Opera will load the file with media=&quot;screen&quot; too.</p>
  <p>Why is this invalid now? Is there another way to give extra CSS to &quot;fullscreen / projection&quot; devices?</p>
