React and CSS3 implement WeChat red envelope opening animation

This time I will bring you React and CSS3 to implement WeChat red envelope opening animation. What are the precautions for React and CSS3 to implement WeChat red envelope opening animation. The following is a practical case, let’s take a look.

WeChat red envelopes have set off a series of marketing crazes. I believe everyone is familiar with this form of red envelopes. In the spirit of entertainment first, here we use React to simply implement the animation effect of opening red envelopes for everyone to join together. Exchange and study

Use CSS3 to draw red envelopes

.redpack {
  height: 450px;
  background: #A5423A;
  width: 300px;
  left: 0;
  top: 0;
  border-radius: 10px;
  margin: 0 auto;
}
.topcontent {
    height: 300px;
    border: 1px solid #BD503A;
    background-color: #BD503A;
    border-radius: 10px 10px 50% 50% / 10px 10px 15% 15%;
    box-shadow: 0px 4px 0px -1px rgba(0,0,0,0.2);
}
#redpack-open {
    width: 100px;
    height: 100px;
    border: 1px solid #FFA73A;
    background-color: #FFA73A;
    border-radius: 50%;
    color: #fff;
    font-size: 20px;
    display: inline-block;
    margin-top: -50px;
    box-shadow: 0px 4px 0px 0px rgba(0, 0, 0, 0.2);
}

<p class=&#39;redpack&#39;>
  <!--  红包的顶部盖子 -->
  <p class="topcontent"></p>
  <!-- 拆红包的按钮 -->
  <p id="redpack-open"></p>
</p>

The effect is as shown in the figure:

Use React to distinguish different state transitions

If implemented with React.js, the red envelope is mainly controlled by judging the state. Now it is Are you waiting to be disassembled or have you already disassembled it? The specific code is as follows

import React from 'react';
class ReadPacket extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            animation: false,
            status: 0  // 0: 等待拆开 1: 拆开后
        };
    }
    render() {
        var bonus = this.props.thanks ? 0 : parseFloat(this.props.surveyInfo.bonus);
        if(this.state.status == 0) {
            return (
                <p className=&#39;redpack-container&#39; id=&#39;redpack-container&#39;>
                    <p className=&#39;redpack&#39;>
                        <p className=&#39;topcontent&#39;>
                            <p id=&#39;redpack-opened&#39;>
                              <p className=&#39;redpack-avatar&#39;>
                                <img src=&#39;http://placehold.it/80x80&#39; alt=&#39;头像&#39; width=&#39;80&#39; height=&#39;80&#39;/>
                              </p>
                            </p>
                            <h2 style={{marginTop: 80, color: &#39;white&#39;}}>奖励</h2>

                             onClick={this.openRedPacket.bind(this)}
                        >
                            <span>拆红包</span>
                        </p>
