布局容器示例

 

栅格系统

　　一个row表示一行（这一行默认分成了12份，每一份你还可以人为的自定义分成12份）

<div class="container">  //左右两边留有空白
    <div class="row">  //一行
        <div class="col-md-6 "></div> // 控制你占当前行的多少列
    </div>
</div>

列偏移

<div class="col-md-offset-3"></div>

浮动

pull-left
pull-right

表格

 <table class="table table-hover table-bordered table-striped"></table>

按钮

<button class="btn btn-success">button</button>  //绿色
<button class="btn btn-info">button</button>  
<button class="btn btn-warning">button</button>
<button class="btn btn-danger">button</button>
<button class="btn btn-primary">button</button>

将a标签设置成按钮模式

<a href="http://www.xiaohuar.com" class="btn btn-primary">Link</a>
btn-block 占父标签100%
