1下载==》cnpm install vue-particles --save-dev 2引入 注册--》main.js//插件
import VueParticles from ‘vue-particles‘ Vue.use(VueParticles)

在使用的时候外层必须要有一个id包裹（重要） 否则展示不出来

<template>
<div class="maxnbox" ref="clcheight">
   
   <!-- 插件开始  外层使用了appp包裹  class="beijing"可以添加一张背景图片 配合css引入-->
  <div id="apppp">

      >
    </vue-particles>
  </div>
  <!-- end -->
