title: Which mode is IE6 if doctype is html as HTML5?
body: <p>If web page has doctype as HTML5.</p>
  
  <pre><code>&lt;!doctype html&gt;
  </code></pre>
  
  <p>Which render mode is it for IE6? </p>
  
  <p>The <strong>document.compatMode</strong> tells <strong>CSS1Compat</strong>. It looks Standard mode, not quirks mode. But, is it true? IE6 is released before HTML5 term is coined. How can IE6 recognize HTML5 doctype?</p>
