html5.js让IE（包括IE6）支持HTML5元素方法

引用Google的html5.js文件

<!--[if IE]>
<script src=”http://html5shiv.googlecode.com/svn/trunk/html5.js”></script>
< ![endif]-->

将上代码复制到head部分，记住一定要是head部分（因为IE必须在元素解析前知道这个元素，所以这个js文件不能在其他位置调用，否则失效）

当然，你也可以把代码拿出来自己看着办：html5.js

最后在css里面加上这段：

/*html5*/
article,aside,dialog,footer,header,section,footer,nav,figure,menu{display:block}
