笔COOL提供的基础 GSAP 项目

## 用途

- 想要简单练习 GSAP
- 展示自己的 GSAP 作品

## 文件

- **index.html**： 网页入口文件（笔COOL目前会编译并运行 index.html 以及它所引用的文件）
- **sytle.css**： 样式文件
- **index.js**： 脚本文件
- **package.json**: npm 包管理文件，你可以继续添加其他依赖包 **【注意：首次引入新依赖可能会报错，稍后再次刷新即可】**
    - 目前已引入的包：
        - `"gsap": "3.14.2"`

## 内容

- 通过 `<link rel="stylesheet" href="./style.css">` 引入样式文件
- 通过 `<script src="./index.js"></script>` 引入脚本文件
- 案例展示了一个通过 GSAP 实现的文字动画效果

## 模板使用
