bootstarp容器和栅格系统

一、bootstrap 容器

container-fluid 流体
container
- 1170
- 970
- 750
- 100%

<div class="container-fluid">流体容器</div>
<div class="container">响应式固定容器</div>

bootstrap响应式查询区间：

1、大于等于768
2、大于等于992
3、大于等于1200

二、bootstrap 栅格系统

bootstrap将页面横向分为12等分，按照12等分定义了适应不同宽度等分的样式类，这些样式类组成了一套响应式、移动设备优先的流式栅格系统：

1、col-lg- 大于1200排成一行，小于1200分别占一行
2、col-md- 大于992排成一行，小于1200分别占一行
3、col-sm- 大于768排成一行，小于992分别占一行
4、col-xs- 始终排列成一行
