  18 // http://caniuse.com/#feat=css-gencontent
  19 //
  20 // For elements that are intended to have both an icon and text, browsers that
  21 // do not support pseudo-selectors will degrade to text-only.
  22 //
  23 // However, icon-only elements do not yet degrade to text-only elements in these
  24 // browsers.
