title: IE8 browser mode vs document mode
body: <p>Can someone please explain the difference between IE8 <strong>browser mode</strong> and <strong>document mode</strong> in simple terms?</p>
  
  <ul>
  <li>What causes the browser mode to change?</li>
  <li><p>What causes the document mode to change?</p></li>
  <li><p>If a user changes the mode(s) via developer tools, does the change remain even if the page is refreshed?</p></li>
  </ul>
  
  <p>I am asking this because we are doing some IE8 testing here, and different people have different combinations of the modes, and i want to try to figure out how this is happening.</p>
