body: <p>What is the difference between the <code>.html</code> and <code>.xhtml</code> file extensions? </p>
  
  <p>What is the benefit of using the <code>.xhtml</code> extension? </p>
  
  <p>Why we are not using the <code>.xhtml</code> extension, is it just because of IE?</p>
  
  <p>What about .xhtml extension with IE 8?</p>
  
  <p>Is <code>.xhtml</code> supported in other browsers besides IE? If yes, then what benefit we will get when all browsers support the <code>.xhtml</code> extension. Will we stop using <code>.html</code>?</p>
  
  <p>Why do we use the XHTML doctype, but save those files using the <code>.html</code> extension?</p>
