使用particles.js制造粒子特效

先上效果图：

使用particles.js2.0版本进行制作。

目录结构

index.html 为主页面，app.js为入口文件，particles.json 为配置文件。

具体配置请参考：GitHub - VincentGarreau/particles.js: A lightweight JavaScript library for creating particles

源码：

index.html：

app.js:

/* particlesJS.load(@dom-id, @path-json, @callback (optional)); */
particlesJS.load("particles-js", "particles.json", function () {
  console.log("callback - particles.js config loaded");
});

particles.json:
