title: HTML 5 w3c validation
body: <p>I validated my website using validator.w3.org  </p>
  
  <p>It reported the following error:</p>
  
  <pre><code>Line 5, Column 67: Bad value X-UA-Compatible for attribute http-equiv on element meta.
  &lt;meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" &gt;
  </code></pre>
  
  <p>If I don't include that META tag, than all IE9 visitors will see my website in Quirks mode, and I want to prevent that.</p>
  
  <p>Any help would be greatly appreciated!</p>
