1- الاكواد المستعملة فى الدرس :
استبدل رابط او وجدته :
<link href='//maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css' rel='stylesheet'/>
بـــ
<script type='text/javascript'>//<![CDATA[
//add Font Awesome
      var cb = function() {
        var l = document.createElement('link'); l.rel = 'stylesheet';
        l.href = '//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css';
        var h = document.getElementsByTagName('head')[0]; h.parentNode.insertBefore(l, h);
      };
      var raf = requestAnimationFrame || mozRequestAnimationFrame ||
          webkitRequestAnimationFrame || msRequestAnimationFrame;
      if (raf) raf(cb);
      else window.addEventListener('load', cb);
//]]></script>



2- اضف كود async='async'  فى روابط اكواد  الجافا سكريب
مثال :
كان هكذا :
<script src="//xxxxxxxxxxxxxxxxxxxxxxxxx.js"></script>
يصبح هكذا :
<script async='async' src="//xxxxxxxxxxxxxxxxxxxxxxxxx.js"></script>




3- اكواد المستعملة للتخلص من مشكل : Leverage browser caching تضاف فوق الكود </head>
