    <title>绝对定位布局</title>
    <style type="text/css">
      .wrap2 div{
            position: absolute;
            min-height: 200px;
        }
        .wrap2 .left{
            left: 0;
            width: 300px;
            background: red;
        }
        .wrap2 .right{
            right: 0;
            width: 300px;
            background: blue;
        }
        .wrap2 .center{
            left: 300px;
            right: 300px;
            background: pink;
        }

</head>
<body>

    <div class="wrap2 wrap">
        <div class="left"></div>
        <div class="center">

        </div>
        <div class="right"></div>

            min-height: 200px;
        }
        .wrap3 .left{            
            flex-basis: 300px;
            background: red;
        }
        .wrap3 .right{            
            flex-basis: 300px;
            background: blue;
        }
        .wrap3 .center{
            flex: 1;
