Typeface.js :hover workaround

var typefacehover = function (){                            
  $(".typeface-js").each(function(){
    //Get all the classes for an element. 
    var elementStyles = $(this).attr('class');
    elementStyles = elementStyles.split(' ');
    //Run through them and check for a :hover color property.
    var hoverColor;                                
    for (var i in elementStyles){                                        
      var temp = getCSSColor('.'+elementStyles[i]+':hover');                           
      if(temp) {
        hoverColor = temp;                                        
      }
    }
    if(hoverColor){
      var element = $(this).html();
      //Duplicate the element, create a new hover version of the element (hidden) and add a container to each one so that we can distinguish between the two.
      var hoverElement = '<div class="typeface-js-hover" style="color:'+hoverColor+';display:none">'+element+'</div>';
      element = '<div class="typeface-js-nohover">'+element+'</div>';
      var newElement = element + hoverElement;
      $(this).html(newElement);
 
      //Add the event listener. You could do fade transitions here if you wanted to be fancy.
      $(this).hover(
        function(){
          $(".typeface-js-nohover",this).hide();
          $(".typeface-js-hover",this).show();
