bootstrap3.3 兼容IE8处理方法

bootstrap是在html5的基础上实现的，要想让IE8兼容，首先要让器兼容html5 ，然后兼容bootstrap，在head中加入以下代码：

最好加载引用额css后边

 <!--{cke_protected}{C}%3C!%2D%2D%20IE8%E5%85%BC%E5%AE%B9%E6%80%A7%E5%A4%84%E7%90%86%E4%BB%A3%E7%A0%81%20%20begin%2D%2D%3E-->
    <!--{cke_protected}{C}%3C!%2D%2D%5Bif%20lt%20IE%209%5D%3E%0A%20%20%20%20%20%20%3Cscript%20src%3D%22%2F%2Fcdn.bootcss.com%2Fhtml5shiv%2F3.7.2%2Fhtml5shiv.min.js%22%3E%3C%2Fscript%3E%0A%20%20%20%20%20%20%3Cscript%20src%3D%22%2F%2Fcdn.bootcss.com%2Frespond.js%2F1.4.2%2Frespond.min.js%22%3E%3C%2Fscript%3E%0A%20%20%20%20%3C!%5Bendif%5D%2D%2D%3E-->
    <!--{cke_protected}{C}%3C!%2D%2D%20Respond.js%20proxy%20on%20external%20server%20%2D%2D%3E-->
    

如果没效果，尝试调整引入文件的先后顺序
