已创建的项目集成 tailwindcss
1.安装依赖
npm install tailwindcss2. 根目录下创建文件tailwind.config.js 初始化文件
// https://unpkg.com/browse/tailwindcss@3.1.6/stubs/defaultConfig.stub.js
/** @type {import('tailwindcss').Config} */

5. vscode 插件 可以直接搜索 Tailwindcss 下载敲代码 样式提示插件
6. 可以直接在 Tailwindcss 官网直接搜索样式 ，非常方便
7 . 常见写法样式举例 h-30 为 height:30 也支持自定义 h-[30px] w-[30px] text-[30px] ，一般在官网搜索 后面会给出值自定义例子
