这几天研究了bootstrap响应式布局,其实现原理如下 :

首先用@media查询当前屏幕的大小,然后根据屏幕大小显示不同样式,样式都是用%定义的。

自己模仿也实现了类似的布局,代码如下:

//html文件
<!DOCTYPE html>
<html>
 <head>
   <meta charset="utf-8">
   <title>自己实现栅格布局</title>
   <link href="css/mystyle.css" rel="stylesheet" type="text/css">
 </head>
 <body>
   <div class="container">
      <div class="row">
        <div class="col-xs-6 col-sm-4">1-1</div>
        <div class="col-xs-6 col-sm-4">1-2</div>
        <div class="col-xs-12 col-sm-4">1-3</div>
      </div>
      <div class="row">
        <div class="col-xs-3 col-sm-3">2-1</div>
        <div class="col-xs-6 col-sm-6">2-2</div>
        <div class="col-xs-3 col-sm-3">2-3</div>
      </div>
      <div class="row">
         <div class="col-xs-2 col-sm-1">3-1</div>
         <div class="col-xs-2 col-sm-1">3-2</div>
         <div class="col-xs-8 col-sm-2">3-3</div>
         <div class="col-xs-3 col-sm-2">3-4</div>
         <div class="col-xs-3 col-sm-6">3-5</div>
      </div>
   </div>
 </body>
</html>

//css文件 *
{ margin:0px; padding:0px; box-sizing: border-box; } .container{ width:100%; max-width: 1201px; } .container,[class*="col-"]{ border:solid 1px #999; } .row:before,.row:after{ content:""; display: table; clear:both; } [class*="col-"]{ float:left; min-height:1px; padding:12px; height:50px; margin:10px; background-color: #eee; font-size:12px; text-align: center; } @media screen and (min-width: 769px){ .col-sm-1 { width:calc(8.333333% - 20px); } .col-sm-2 { width:calc(16.666666% - 20px); } .col-sm-3 { width:calc(24.999999% - 20px); } .col-sm-4 { width:calc(33.333332% - 20px); } .col-sm-5 { width:calc(41.666665% - 20px); } .col-sm-6 { width:calc(50% - 20px); } .col-sm-7{ width:calc(58.333331% - 20px); } .col-sm-8 { width:calc(66.666664% - 20px); } .col-sm-9 { width:calc(74.999997% - 20px); } .col-sm-10 { width:calc(83.333333% - 20px); } .col-sm-11{ width:calc(91.666666% - 20px); } .col-sm-12 { width:calc(100% - 20px); } } @media screen and (max-width: 768px){ .col-xs-1 { width:calc(8.333333% - 20px); } .col-xs-2 { width:calc(16.666666% - 20px); } .col-xs-3 { width:calc(24.999999% - 20px); } .col-xs-4 { width:calc(33.333332% - 20px); } .col-xs-5 { width:calc(41.666665% - 20px); } .col-xs-6 { width:calc(50% - 20px); } .col-xs-7{ width:calc(58.333331% - 20px); } .col-xs-8 { width:calc(66.666664% - 20px); } .col-xs-9 { width:calc(74.999997% - 20px); } .col-xs-10 { width:calc(83.333333% - 20px); } .col-xs-11{ width:calc(91.666666% - 20px); } .col-xs-12 { width:calc(100% - 20px);; } }
