### 输入框组： ###

#### 基本用法： ####

//form-control 占满  
    //input-group:输入框组
    //input-group-addon：输入框前加入一个前缀
    　　<div class="input-group">
            <span class="input-group-addon">@</span>
            <input type="text" class="form-control">
            <span class="input-group-addon">@</span>
        </div>

## 导航 ##

Bootstrap 中的导航组件都依赖同一个 `.nav` 类，状态类也是共用的。改变修饰类可以改变样式。

###  标签页： ###

li：标签内部是一个链接或按钮

<ul class="nav nav-tabs">{#选项卡nav-tabs  只写nav不行#}
            <li><a href="">111</a></li> 
            <li><a href="">222</a></li>
            <li><a href="">333</a></li>
        </ul>
