Bootstrap的使用及案例

注意这里我们使用的是Bootstrap3
进入Bootstrap3使用手册

先将样式表导入

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><link rel="stylesheet" href="/static/plugins/bootstrap3/css/bootstrap.css">
</head>
<body>

导航条

进入Bootstrap3使用手册,点击组件，然后右边找到导航条，复制这一串代码，粘贴到body标签内

即可得到如下效果

栅格系统

把整体划分了12格
分类

非响应式

        <div class="col-xs-6" style="background-color: red">1</div><div class="col-xs-6" style="background-color: green">2</div>

特点：无论如何修改页面大小，其相对不变

2. 响应式

后面三个为响应式

特点：当屏幕宽度不同，会做出不同的响应

列偏移

         <div class="col-sm-offset-2 col-lg-6" style="background-color: red">1</div>

container

自己写网站的时候，前端页面的修改不可避免。无论用什么框架，都无法避免要用到container。在h5出现之前，我们用的最频繁的html标签是div，span等，可以看到目前主流的css框架，比如bootstrap，用到这样的语义化标识，container是为了分块，更好的设计。

加上container会居中显示， container-fluid会平铺

    <div class="container"><div class="col-lg-9">left</div><div class="col-lg-3">right</div></div>

效果如下

面板

以下面板即用了Bootstrap的导航和栅格系统，面板，媒体对象，分页进行构建的
