   8 // Support for responsive views via media queries is kind of borked in IE10, for
   9 // Surface/desktop in split view and for Windows Phone 8. This particular fix
  10 // must be accompanied by a snippet of JavaScript to sniff the user agent and
  11 // apply some conditional CSS to *only* the Surface/desktop Windows 8. Look at
  12 // our Getting Started page for more information on this bug.
