学习bootstrap框架，主要是为了集成好的响应式框架，及其兼容性。
但是按bootstrap中文站的说明文档 制作了一个栅格布局的test.html后，怎么测试都不成功，在ie8下一直看不到媒体查询的效果，纠结了一整天的respond.js的失效问题，最后一气之下，把他的整个案例在ie8下复制了源代码，在本地一个个删掉测试，最后郁闷的发现，原来他连接到bootstrap网站的css是根本原因，改成本地的bootstrap.css就成功了。（坑爹呢！）
下面是中文站提供的基本模版：
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap 101 Template</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Bootstrap -->
<link rel="stylesheet" href="http://cdn.bootcss.com/twitter-bootstrap/3.0.3/css/bootstrap.min.css"> <!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries -->
<!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
<!--[if lt IE 9]>
<script src="http://cdn.bootcss.com/html5shiv/3.7.0/html5shiv.min.js"></script>
<script src="http://cdn.bootcss.com/respond.js/1.3.0/respond.min.js"></script>
<![endif]-->
</head>
<body>
<h1>Hello, world!</h1>
<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="http://cdn.bootcss.com/jquery/1.10.2/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="http://cdn.bootcss.com/twitter-bootstrap/3.0.3/js/bootstrap.min.js"></script>
</body>
</html>
然后我加入了测试的栅格布局
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap 101 Template</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Bootstrap -->
<link rel="stylesheet" href="http://cdn.bootcss.com/twitter-bootstrap/3.0.3/css/bootstrap.min.css"> <!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries -->
<!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
<!--[if lt IE 9]>
<script src="http://cdn.bootcss.com/html5shiv/3.7.0/html5shiv.min.js"></script>
<script src="http://cdn.bootcss.com/respond.js/1.3.0/respond.min.js"></script>
<![endif]-->
</head>
<body>
<div class="container">
<div class="row">
<div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div> <!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
<div class="row">
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div> <!-- Columns are always 50% wide, on mobile and desktop -->
<div class="row">
<div class="col-xs-6">.col-xs-6</div>
<div class="col-xs-6">.col-xs-6</div>
</div>
</div>
<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="http://cdn.bootcss.com/jquery/1.10.2/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="http://cdn.bootcss.com/twitter-bootstrap/3.0.3/js/bootstrap.min.js"></script>
</body>
</html>
最后改掉bootstrap.css，在本地引用后正常显示。
虽然不怎么相信是中文站出错，但是事实就是这样，也许是我未能学习到的一些问题吧？
