title: Forcing IE7 into standards rendering mode (not quirks)
body: <p>I'm having display issues in IE7 due to it rendering in quirks mode.  I've confirmed this by displaying "document.compatMode" and getting back "BackCompat" as opposed to "CSS1Compat".  Using IE8 and reverting to IE7 works, because that keeps it out of quirks.  In plain IE8 I have it fixed by forcing the rendering mode with the X-UA-Compatible header, but this does not work for IE7.  The other browsers also display in quirks, but unlike IE this does not put them into pseudo-IE5.5 mode, so they still render fine.  </p>
  
  <p>How can I force IE7 to render in standards rendering mode and not quirks?  I've tried setting the DOCTYPE to a number of different options and I'm not adding the xml prologue.
  Thanks in advance for any replies.</p>
