Boostrap前端框架

Bootstrap它是基于jQuery，也就意味着你在用bootstrap要先导入jQuery文件！！！
    
    建议使用3.X版本，不要轻易使用最新版
    
    修改页面样式其实就是修改类属性
    
    
    
    布局容器
    <div class="container "></div>  左右有固定留白
    <div class="container-fluid c1"></div>  全屏展示
    
    
    
    栅格系统
    一个row就表示一行(这一行默认给你均分成了12份,每一份你还可以均分成12份)
    
    首先使用bootstrap先写一个布局容器
    <div class='container'></div>
    <div class='container-fluid'></div>
    
    
    <div class="container">
        <div class="row">  一行
            <div class="col-md-6 c1"></div>  控制你占当前行的多少列
        
    列偏移
    col-md-offset-3 
    
    浮动
    pull-left
    pull-right
    
    表格
    <table class="table table-hover table-bordered table-striped">
    
    按钮
            <button class="btn btn-success">button</button>
            <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>
            <a href="http://www.xiaohuar.com" class="btn btn-primary">Link</a>
            
            
            btn-block 占父标签100%

<!-- 先到bootstrap里将代码拷贝过来，然后将col-md-6改为col-md-4（输入框变短了） 加上col-md-offset-4（向右偏移） 和c1（自己写的样式类）
email 和password换成用户名和密码
<label for="inputEmail3" class="col-sm-2 control-label">用户名</label>改为
<label for="inputEmail3" class="col-sm-3 control-label"> 不然用户名这三个字不够位置
col-sm-3字体改小了
 <div class="col-sm-10">改为 <div class="col-sm-9">
 密码那里也一样  剩下的两处也改了  （col-md 或 col-sm 等 后面的两个数加起来等于12 如3+9=12就好了）
 然后再将body背景颜色改掉
 然后在<label for="inputEmail3" class="col-sm-3 control-label">用户名</label>加入<h3 class="text-center">会员登录</h3>-->
 <!--<form class="form-horizontal">-->
                <!--<from action="">-->

                <!--</from>-->
<!--加入以上代码在<div class="col-md-4 col-md-offset-4 c1"> 下，测试加入class="form-control" 边框角变圆了
  <div class="form-group ">加入 has-error用户名飘红
   在用户名输入框之下写上<span class="error help-block">用户名错误</span>
    <button type="submit" class="btn">Sign in<i class="fa fa-bath" aria-hidden="true"></i></button>加上btn-primary active
    会员登录后加上<span class="glyphicon glyphicon-user"></span>-->
