我完全按照这些指示去做：
https://tailwindcss.com/docs/installation
但是下拉菜单应该是这样的
https://tailwindui.com/components/application-ui/elements/dropdowns
看起来还是垃圾

我安装了Tailwind并使用init：

我这样填写"tailwind.config.js"：

• • 顺风配置js**

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./src/components/DropdownVue/DropdownVue.vue"], <---INCLUDED  DROPDOWN FILE
  theme: {
    extend: {},
  },
  plugins: [],
};

我创建了一个"index.css"，并将Tailwind模块导入其中，如下所示：

• • 索引. css**

@tailwind base;
@tailwind components;  <-----INCLUDED IMPORTS
@tailwind utilities;

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  font-family: "Noto Serif", serif, Ariel, Helvetica, sans-serif;
  background: #d7d7d7;
}

img {
  width: 100%;
  object-fit: contain;
}

@import url("https://fonts.googleapis.com/css2?family=Noto+Serif&display=swap");

我启动了构建过程并得到了一个"output.css"文件
https://i.imgur.com/mOKDwuc.png
我在我的"index.html"文件中包含了这样的内容：

<link href="/dist/output.css" rel="stylesheet">

在这一点上，你应该已经完成了，你的顺风组件应该按照那些说明工作。
但是，他们没有工作，然后我找到了一个更具体的页面安装Tailwind与Vue + Vite：
https://tailwindcss.com/docs/guides/vite
而且方向也差不多，只是它对NPM安装是这样说的：

npm install -D tailwindcss postcss autoprefixer

以前我只安装了"tailwindcss"，所以我运行了其他2个软件包的安装，希望能修复它，但它没有。
我哪里说错了？谁能帮我修一下？
这是所有相关代码：

• • 顺风配置js**

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./src/components/DropdownVue/DropdownVue.vue"], <---INCLUDED FILE
  theme: {
    extend: {},
  },
  plugins: [],
};

• • 索引. css**

@tailwind base;

  padding: 0;
  box-sizing: border-box;
}

body {
  font-family: "Noto Serif", serif, Ariel, Helvetica, sans-serif;
  background: #d7d7d7;
}

img {
  width: 100%;
  object-fit: contain;
}

@import url("https://fonts.googleapis.com/css2?family=Noto+Serif&display=swap");
