有一些小的而且毕竟规则的icon，其实完全可以用CSS渲染出，不用那么多UI图片了，把工作交给客户端去渲染，减少图片加载的时间，让页面加载更快

1、画一个正方形（改变长宽，就是长方形了）

#square {
  width: 100px;
  height: 100px;
  background: red;
}

2、画一个圆

#circle {
  width: 100px;
  height: 100px;
  background: red;
  border-radius: 50%
}

3、画一个椭圆

 #oval {
   width: 200px;
   height: 100px;
   background: red;
   border-radius: 100px / 50px;
}

4、画一个三角形

    #triangle-up {
      width: 0;
      height: 0;
      border-left: 50px solid transparent;
      border-right: 50px solid transparent;
      border-bottom: 100px solid red;
    }

5、画一个倒三角形

    #triangle-down {
      width: 0;
      height: 0;
      border-left: 50px solid transparent;
      border-right: 50px solid transparent;
      border-top: 100px solid red;
    }

6、画一个向左横的三角形

    #triangle-left {
      width: 0;
      height: 0;
      border-top: 50px solid transparent;
      border-right: 100px solid red;

      border-bottom: 50px solid transparent;
    }

      border-bottom: 70px solid red;
      border-left: 100px solid transparent;
      transform: rotate(35deg);
    }
    #star-five:before {
      border-bottom: 80px solid red;
      border-left: 30px solid transparent;
      border-right: 30px solid transparent;
      position: absolute;
      height: 0;
      width: 0;
      top: -45px;
      left: -65px;
      display: block;
      content: '';
      transform: rotate(-35deg);
    }
    #star-five:after {
