Bootstrap 洼地

洼地（Well）样式的效果和大屏幕展播Jumbotron样式类似，不同点是well样式有了边框设置，并且默认高度是自适应文本的高度。示例代码：

<div class="well">   <p> sorry I have no word to say</p>   <blockquote>this is a 引用内容</blockquote></div>

效果：

可以设置洼地的大小：

<div class="well well-lg">   <p> sorry I have no word to say</p>   <blockquote>this is a 引用内容</blockquote></div><div class="well">   <p> sorry I have no word to say</p>   <blockquote>this is a 引用内容</blockquote></div><div class="well well-sm">   <p> sorry I have no word to say</p>   <blockquote>this is a 引用内容</blockquote></div>
