移动端总结 新增页面标签
1新增结构标签：（我们以前布局页面经常用到的是div或者span等，但是这些没有语义化）2功能标签：3兼容IE低版本浏览器的办法(IE低版本把h5新增标签解析成了行元素)4兼容代码（html5shiv.min.js）

3兼容IE低版本浏览器的办法(IE低版本把h5新增标签解析成了行元素)
1手动创建：在js中创建h5新增标签，css中给h5标签添加display：block属性 举例：
<script type
="text/javascript">
var e
=("abbr,article,aside,audio,canvas,datalist,details,"+"figure,footer,header,hgroup,mark,menu,meter,nav,output,"+"progress,section,time,video").split(',');
for(var i
=0;i
<e
.length
;i
++) {
document
.createElement(e
[i
]);
}
</script
>
