  常见的卡券样式如下:
 
  
  使用伪元素实现(Less 版本)
 
 
  ticket.less
 
  .ordinary-mixins-ticket-horizontal(@width,@height,@r,@top, @color) {
    position: relative;
    box-sizing: border-box;
    padding: 0 @r;
    width: @width;
    height: @height;
    background-clip: content-box;
    background-color: @color;
 
    &::before {
      position: absolute;
      top: 0;
      left: 0;
      content: "";
      display: block;
      width: @r + 1px;
      height: 100%;
      background: radial-gradient(@r circle at left @top, transparent @r, @color @r + 1px);
    }
 
    &::after {
      position: absolute;
      top: 0;
      right: 0;
      content: "";
      display: block;
      //这里的 @r + 1px 是为了避免某些百分百比缩放页面时,出现空隙
      width: @r + 1px;
      height: 100%;
      //这里的 @r + 1px 是为了防止出现锯齿
      background: radial-gradient(@r circle at right @top, transparent @r, @color @r + 1px);
    }
  }
 
  .parent {
    .ordinary-mixins-ticket-horizontal(200px, 200px, 10px, 150px, #fc3a28);
  }
  .child {
    line-height: 200px;
  }
  App.js
 
  import React from 'react';

                  justifyContent: "center",
                  alignItems: "center",
                  height: 600
              }
          }>
