    toggleIcon = $(".nav-toggle span");

function toggleThatNav() {
  if (menu.hasClass("show-nav")) {
    if (!Modernizr.csstransforms) {
      menu.removeClass("show-nav");
      toggle.removeClass("show-nav");
      menu.animate({

      toggle.addClass("show-nav");
      menu.css("right", "0px");

      toggle.addClass("show-nav");
    } 
  }
}

function changeToggleClass() {
  toggleIcon.toggleClass("fa-times");

}

$(function() {
  toggle.on("click", function(e) {
    e.stopPropagation();
    e.preventDefault();
    toggleThatNav();
    changeToggleClass();
