Particles.js是一款基于HTML5 Canvas画布的轻量级粒子动画插件，可以设置粒子的形状、旋转、分布、颜色等属性，还可以动态添加粒子，效果非常炫酷，能和鼠标互动吸附或者是躲避鼠标指针。

使用方法

1、该粒子动画库插件使用方法非常简单，首先要在页面中引入particles.js文件。

<script src="js/particles.js"></script>

2、在页面中使用一个div来作为放置粒子的容器。

<div id="particles-js"></div>

3、通过particlesJS.load()方法加载配置文件

particlesJS.load(‘particles-js‘, ‘assets/particles.json‘, function() {
  console.log(‘callback - particles.js config loaded‘);
});

4、编写particles.json配置文件

    "number": {
      "value": 80,
      "density": {
        "enable": true,
        "value_area": 800
