  16 // This includes support for IE8.

  19 // For elements that are intended to have both an icon and text, browsers that
  20 // do not support pseudo-selectors will degrade to text-only.
  21 //
  22 // However, icon-only elements do not yet degrade to text-only elements in these
  23 // browsers.
