Improved web font loader code to prevent FOUT

gistfile1.js

// Custom web font loader inspired by the TypeKit loader.
WebFontConfig = {
  fontdeck: {
    id: FONTDECK_ID
  },
  active: function() {
    clearTimeout(this._timeout);
  }
};
(function() {
  var a = document.getElementsByTagName("html")[0];
  a.className += " wf-loading";
  WebFontConfig._timeout = setTimeout(function () {
      a.className = a.className.replace(/(\s|^)wf-loading(\s|$)/g, ""), a.className += " wf-inactive"
  }, 3000);
  var wf = document.createElement('script');
  wf.src = '//ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
  wf.type = 'text/javascript';
  wf.async = 'true';
  var s = document.getElementsByTagName('script')[0];
  s.parentNode.insertBefore(wf, s);
})();
