Question

bootstrap 貌似对 IE7，IE8 支持得不好，有什么解决方案

Answer 1

　　其实就算不考虑IE，你的网站如果真正是个产品的话，bootstrap中能直接用的也不多。bootstrap有它的场景。
　　但是它提供了一种思路，一种做这件事的思路和方式。
　　我们自己可以搞一套出来，适合自己的项目和网站的需要。
　　我觉得是这样的。
　　这里引一个老外的解决方案：
　　... to hope for ie6 support, but I think that it will be difficult to make bootstrap compatible. I'm using a js library called moderizr.js to add classes to the html tag that tells what the browsers capabilities are and then making special css classes that will allow ie6 to gracefully downgrade as much as possible. I think that it is an alright solution. It won't look exactly the same, but it still should work.
