title: what is causing IE8 to render in IE7 mode by default
body: <p>this site : <a href="http://medisra.sideradesign.com" rel="nofollow">http://medisra.sideradesign.com</a>
  it is rendering in IE7 document mode by default.
  Is this due to a CSS or HTML validation error? how can I identify what's causing it?
  thanks</p>
