项目快速启动

安装

你可以通过以下方式将 particles.js 集成到你的项目中：

通过 CDN 引入：

<script src="https://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js"></script>

通过 npm 安装：
```
npm install particles.js
```

基本使用

HTML 结构：
```
<div id="particles-js"></div>
```

JavaScript 配置：

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

配置文件 particles.json：
