     有时候在网页设计中会涉及到很多看上去很繁琐的设计图,这时候都会很让人头疼,那么这时候伪类就可以来帮助你解决问题了。

    下面有一段实例大家可以参考一下;

     1 <!DOCTYPE html>
     2 <html>
     3     <head>
     4         <meta charset="UTF-8">
     5         <title></title>
     6     </head>
     7     <style type="text/css">
     8         .box{
     9             width: 800px;
    10             height: 800px;
    11             margin: 0 auto;
    12         }
    13         p{
    14             line-height: 1.5;
    15         }
    16         *{
    17             margin: 0;padding: 0;
    18         }
    19         .clearfix{
    20             clear: both;
    21         }
    22         .left,.content,.right{
    23             width: 200px;float: left;position:relative;
    24         }
    25         .content{
    26             margin:80px 50px;
    27         }
    28         .left::after{
    29             content:"";width:1px;height: 160px;position:absolute;top:50px;right:0px;background:deeppink;

    48         
    49         .right-one::before{
    50             content:"";width:50px;height: 1px;position:absolute;top:30px;left:-50px;background:deeppink;
    51         }
    52         
    53         
    54     </style>
    55     <body>
    56         <div class="box">
