title: Change hover background colour in dropdown menu for IE 10 and 11
body: <p>Does anyone know if it's possible to change the colour of the highlighting in dropdown menus for IE 10 and 11?</p>
  
  <p>IE 9 highlights with a blue background whereas IE 10 and 11 highlight with grey.</p>
  
  <p>I'd like to highlight the selection the user is hovering over blue like in IE 9.</p>
