其中的代码如下，通过JS创建HTML5标签
<!--[if IE]>
<script type="text/javascript">
(function(){if(!/*@cc_on!@*/0)return;var e ="abbr,article,aside,audio,canvas,datalist,details,dialog,eventsource,figure,footer,header,hgroup,mark,menu,meter,nav,output,progress,section,time,video".split(','),i=e.length;while(i--){document.createElement(e[i])}})();
</script>
<![endif]-->
其中的代码如下，这些标签本身就是块级标签，所以把这些标签转成块级标签
header,nav,aside,article,footer{ display:block;}
