title: How to detect HTML 5 compatibility in browser
body: <p>What is the best way to detect browser compatibility for HTML 5 syntax? And prompt the user if the browser is not compatible?</p>
  
  <p>I understand <a href="http://diveintohtml5.info/everything.html" rel="noreferrer">the tutorial which shows how to test browser compatibility for HTML5</a>. But I am curious to know if that is the only way? Do I need to inspect each and every element?</p>
