常用的一些css实现的小效果，比如三角形，小三角，阴影等

1. css实现三角形

<!DOCTYPE html>
<html>
 <head>
  <title>little triangle </title>
  <meta charset="utf-8">
  <style>
    div{width:0;height:0;border:50px solid transparent;}
    div:nth-child(1){border-left-color:red;}
    div:nth-child(2){border-top-color:red;}
    div:nth-child(3){border-bottom-color:red;}
    div:nth-child(4){border-right-color:red;}

    div{float:left;}
  </style>
 </head>
 <body>
  <div></div><div></div><div></div><div></div>
 </body>
</html>

 

2. hover时显示阴影

<!DOCTYPE html>
<html>
<head lang="en">
  <meta charset="UTF-8">
  <title>hovershadow</title>
  <style>
    .shadow{
      transition: all 0.15s linear;
    }
    .shadow:hover{
      box-shadow: 0px 5px 20px #ddd;
    }
    .box{
      margin: 30px auto;
      width: 200px;
      height: 200px;
      border:1px solid #ddd;
      border-radius: 10px;
      padding: 10px;
    }
  </style>
</head>
<body>
<div class="box shadow">
  <div class="title">这里是标题</div>
  <div class="content">这里是内容区</div>
</div>
</body>
</html>
