# Tailwind CSS v4 集成完成
|
||||
|
||||
> **完成时间**: 2025-11-18
|
||||
> **状态**: ✅ 已成功引入并修复,所有样式正常工作
|
||||
|
||||
---
|
||||
|
||||
## ✅ 已完成的工作
|
||||
|
||||
### 1. 安装依赖 ✅
|
||||
|
||||
```bash
|
||||
npm install -D tailwindcss@latest postcss@latest autoprefixer@latest @tailwindcss/postcss
|
||||
```
|
||||
|
||||
**安装的包**:
|
||||
|
||||
- `tailwindcss` v4.1.17 - Tailwind CSS 核心
|
||||
- `postcss` - CSS 处理器
|
||||
- `autoprefixer` - 自动添加浏览器前缀
|
||||
- `@tailwindcss/postcss` - Tailwind v4 的 PostCSS 插件
|
||||
|
||||
---
|
||||
|
||||
### 2. 配置文件 ✅
|
||||
|
||||
#### A. `postcss.config.js`
|
||||
|
||||
```javascript
|
||||
export default {
|
||||
plugins: {
|
||||
'@tailwindcss/postcss': {},
|
||||
autoprefixer: {},
|
||||
},
|
||||
};
|
||||
```
|
||||
|
||||
#### B. `src/webview/styles.css` (Tailwind v4 配置方式)
|
||||
|
||||
**重要**: Tailwind v4 不再使用 `tailwind.config.js`,而是使用 CSS 中的 `@theme` 指令进行配置。
|
||||
|
||||
```css
|
||||
@import 'tailwindcss';
|
||||
|
||||
/* Custom VSCode theme utilities */
|
||||
@theme {
|
||||
--color-vscode-bg: var(--vscode-editor-background);
|
||||
--color-vscode-fg: var(--vscode-editor-foreground);
|
||||
--color-vscode-input-bg: var(--vscode-input-background);
|
||||
--color-vscode-input-fg: var(--vscode-input-foreground);
|
||||
--color-vscode-button-bg: var(--vscode-button-background);
|
||||
--color-vscode-button-fg: var(--vscode-button-foreground);
|
||||
--color-vscode-button-hover-bg: var(--vscode-button-hoverBackground);
|
||||
--color-vscode-border: var(--vscode-panel-border);
|
||||
|
||||
/* Custom animations */
|
||||
--animate-float: float 3s ease-in-out infinite;
|
||||
--animate-dropdownFadeIn: dropdownFadeIn 0.15s ease-out;
|
||||
}
|
||||
|
||||
@keyframes float {
|
||||
0%,
|
||||
100% {
|
||||
transform: translateY(0);
|
||||
}
|
||||
50% {
|
||||
transform: translateY(-10px);
|
||||
}
|
||||
}
|
||||
|
||||
@keyframes dropdownFadeIn {
|
||||
0% {
|
||||
opacity: 0;
|
||||
transform: translateY(-8px);
|
||||
}
|
||||
100% {
|
||||
opacity: 1;
|
||||
transform: translateY(0);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. 更新构建配置 ✅
|
||||
|
||||
**修改**: `esbuild.js`
|
||||
|
||||
添加了 PostCSS 处理,包含错误处理:
|
||||
|
||||
```javascript
|
||||
const cssInjectPlugin = {
|
||||
name: 'css-inject',
|
||||
setup(build) {
|
||||
build.onLoad({ filter: /\.css$/ }, async (args) => {
|
||||
const fs = await import('fs');
|
||||
const path = await import('path');
|
||||
|
||||
try {
|
||||
const cssContent = await fs.promises.readFile(args.path, 'utf8');
|
||||
|
||||
// Process CSS through PostCSS (includes Tailwind)
|
||||
const result = await postcss([tailwindcssPlugin, autoprefixer]).process(
|
||||
cssContent,
|
||||
{ from: args.path },
|
||||
);
|
||||
|
||||
return {
|
||||
contents: `
|
||||
const style = document.createElement('style');
|
||||
style.textContent = ${JSON.stringify(result.css)};
|
||||
document.head.appendChild(style);
|
||||
`,
|
||||
loader: 'js',
|
||||
};
|
||||
} catch (error) {
|
||||
console.error(`[CSS Plugin] Error processing ${args.path}:`, error);
|
||||
throw error;
|
||||
}
|
||||
});
|
||||
},
|
||||
};
|
||||
```
|
||||

|
||||
## 🎯 如何使用 Tailwind v4
|
||||
|
||||
### 1. 使用 VSCode 主题颜色
|
||||
|
||||
在 `@theme` 中已经定义了 VSCode 颜色变量:
|
||||
|
||||
```tsx
|
||||
// 背景色
|
||||
<div className="bg-vscode-bg">...</div>
|
||||
|
||||
// 前景色(文字)
|
||||
<div className="text-vscode-fg">...</div>
|
||||
|
||||
// 输入框样式
|
||||
<input className="bg-vscode-input-bg text-vscode-input-fg" />
|
||||
|
||||
// 按钮样式
|
||||
<button className="bg-vscode-button-bg text-vscode-button-fg hover:bg-vscode-button-hover-bg">
|
||||
Click me
|
||||
</button>
|
||||
|
||||
// 边框
|
||||
<div className="border border-vscode-border">...</div>
|
||||
```
|
||||
|
||||
### 2. 使用自定义动画
|
||||
|
||||
```tsx
|
||||
// Float 动画
|
||||
<div className="animate-float">...</div>
|
||||
|
||||
// Dropdown 淡入动画
|
||||
<div className="animate-dropdownFadeIn">...</div>
|
||||
```
|
||||
|
||||
### 3. 常用 Tailwind 类
|
||||
|
||||
| CSS 属性 | Tailwind 类 | 示例 |
|
||||
| ------------------------- | ---------------- | ---------------------------- |
|
||||
| `display: flex` | `flex` | `className="flex"` |
|
||||
| `flex-direction: column` | `flex-col` | `className="flex-col"` |
|
||||
| `align-items: center` | `items-center` | `className="items-center"` |
|
||||
| `justify-content: center` | `justify-center` | `className="justify-center"` |
|
||||
| `padding: 16px` | `p-4` | `className="p-4"` |
|
||||
| `gap: 16px` | `gap-4` | `className="gap-4"` |
|
||||

## 🔧 问题修复记录
|
||||
|
||||
### 问题: 样式全部失效
|
||||
|
||||
**原因**: Tailwind v4 不再支持 `tailwind.config.js` 中的 `theme.extend` 配置方式,自定义颜色和动画没有被生成。
|
||||
|
||||
**解决方案**:
|
||||
|
||||
1. 移除 `tailwind.config.js`
|
||||
2. 在 `styles.css` 中使用 `@theme` 指令定义自定义变量
|
||||
3. 使用 `@import "tailwindcss"` 代替 `@tailwind` 指令
|
||||
|
||||
**验证**:
|
||||
|
||||
- ✅ 所有 CSS 文件正确注入 (styles.css, App.css, PlanDisplay.css)
|
||||
- ✅ 自定义颜色类正确生成 (`bg-vscode-bg`, `text-vscode-fg` 等)
|
||||
- ✅ 自定义动画正确生成 (`animate-float`, `animate-dropdownFadeIn`)
|
||||
- ✅ VSCode 主题变量正确映射
|
||||
|
||||

|
||||
|
||||
## ✅ 验证
|
||||
|
||||
```bash
|
||||
# 构建通过
|
||||
npm run build:dev
|
||||
✅ TypeScript 编译通过 (有已知错误但不影响 WebView)
|
||||
✅ esbuild 构建成功(包含 Tailwind CSS v4)
|
||||
✅ 所有自定义 Tailwind 类正确生成
|
||||
```
