Known Issues This Skill Prevents

本技能可避免的已知问题

tw-animate-css import error (deprecated in v4)
Duplicate @layer base blocks (shadcn init adds its own)
Wrong template selection (vanilla TS vs React)
Missing post-init cleanup (incompatible CSS rules)
Wrong plugin syntax (using @import or require() instead of @plugin directive)

All of these are handled automatically when the skill is active.

tw-animate-css导入错误（v4中已废弃旧版本）
重复的@layer base块（shadcn init会自动添加）
模板选择错误（原生TS和React混淆）
初始化后缺少清理步骤（不兼容的CSS规则）
插件语法错误（使用@import或require()而非@plugin指令）

技能启用后所有这些问题都会自动处理。

{
  "tailwind": {
    "config": "",              // ← CRITICAL: Empty for v4
    "css": "src/index.css",
    "baseColor": "slate",      // Base color palette
    "cssVariables": true,
    "prefix": ""               // No prefix for utility classes
  }
}

json

{
  "tailwind": {
    "config": "",              // ← 关键：v4版本此处留空
    "css": "src/index.css",
    "baseColor": "slate",      // 基础调色板
    "cssVariables": true,
    "prefix": ""               // 工具类无前缀
  }
}

4. Delete tailwind.config.ts

4. 删除tailwind.config.ts

bash

rm tailwind.config.ts  # v4 doesn't use this file

bash

rm tailwind.config.ts  # v4不需要这个文件

The Four-Step Architecture (CRITICAL)

四步架构（核心要求）

This pattern is mandatory - skipping steps will break your theme.

该模式是强制要求 - 跳过步骤会导致主题失效。

Step 1: Define CSS Variables at Root Level

步骤1：在根级别定义CSS变量

css

/* src/index.css */
@import "tailwindcss";

:root {
  --background: hsl(0 0% 100%);      /* ← hsl() wrapper required */
  --foreground: hsl(222.2 84% 4.9%);
  --primary: hsl(221.2 83.2% 53.3%);
  /* ... all light mode colors */
}

.dark {
  --background: hsl(222.2 84% 4.9%);
  --foreground: hsl(210 40% 98%);
  --primary: hsl(217.2 91.2% 59.8%);
  /* ... all dark mode colors */
}

Critical Rules:

✅ Define at root level (NOT inside
```
@layer base
```
)
✅ Use
```
hsl()
```
wrapper on all color values
✅ Use
```
.dark
```
for dark mode (NOT
```
.dark { @theme { } }
```
)

css

/* src/index.css */
@import "tailwindcss";

:root {
  --background: hsl(0 0% 100%);      /* ← 必须用hsl()包裹 */
  --foreground: hsl(222.2 84% 4.9%);
  --primary: hsl(221.2 83.2% 53.3%);
  /* ... 所有亮色模式颜色 */
}

.dark {
  --background: hsl(222.2 84% 4.9%);
  --foreground: hsl(210 40% 98%);
  --primary: hsl(217.2 91.2% 59.8%);
  /* ... 所有暗色模式颜色 */
}

核心规则:

✅ 在根级别定义（不要放在
```
@layer base
```
内部）
✅ 所有颜色值都用
```
hsl()
```
包裹
✅ 暗色模式用
```
.dark
```
（不要用
```
.dark { @theme { } }
```
）

Step 2: Map Variables to Tailwind Utilities

步骤2：将变量映射到Tailwind工具类

css

@theme inline {
  --color-background: var(--background);
  --color-foreground: var(--foreground);
  --color-primary: var(--primary);
  /* ... map ALL CSS variables */
}

Why This Is Required:

Generates utility classes (
```
bg-background
```
,
```
text-primary
```
)
Without this,
```
bg-primary
```
etc. won't exist

css

@theme inline {
  --color-background: var(--background);
  --color-foreground: var(--foreground);
  --color-primary: var(--primary);
  /* ... 映射所有CSS变量 */
}

为什么需要这一步:

生成工具类（
```
bg-background
```
、
```
text-primary
```
）
没有这一步，
```
bg-primary
```
等类不会存在

Step 3: Apply Base Styles

步骤3：应用基础样式

css

@layer base {
  body {
    background-color: var(--background);  /* NO hsl() here */
    color: var(--foreground);
  }
}

Critical Rules:

✅ Reference variables directly:
```
var(--background)
```
❌ Never double-wrap:
```
hsl(var(--background))
```

css

@layer base {
  body {
    background-color: var(--background);  /* 此处不要加hsl() */
    color: var(--foreground);
  }
}

核心规则:

✅ 直接引用变量：
```
var(--background)
```
❌ 不要双层包裹：
```
hsl(var(--background))
```

Step 4: Result - Automatic Dark Mode

步骤4：效果 - 自动暗黑模式

tsx

<div className="bg-background text-foreground">
  {/* No dark: variants needed - theme switches automatically */}
</div>

tsx

<div className="bg-background text-foreground">
  {/* 不需要dark:前缀 - 主题会自动切换 */}
</div>

Dark Mode Setup

暗黑模式设置

1. Create ThemeProvider

1. 创建ThemeProvider

See

reference/dark-mode.md

for full implementation or use template:

typescript

// Copy from: templates/theme-provider.tsx

完整实现请查看

reference/dark-mode.md

或使用模板：

typescript

// 复制自: templates/theme-provider.tsx

2. Wrap Your App

2. 包裹你的应用

typescript

// src/main.tsx
import { ThemeProvider } from '@/components/theme-provider'

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <ThemeProvider defaultTheme="dark" storageKey="vite-ui-theme">
      <App />
    </ThemeProvider>
  </React.StrictMode>,
)

typescript

// src/main.tsx
import { ThemeProvider } from '@/components/theme-provider'

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <ThemeProvider defaultTheme="dark" storageKey="vite-ui-theme">
      <App />
    </ThemeProvider>
  </React.StrictMode>,
)

3. Add Theme Toggle

3. 添加主题切换按钮

bash

pnpm dlx shadcn@latest add dropdown-menu

See

reference/dark-mode.md

for ModeToggle component code.

bash

pnpm dlx shadcn@latest add dropdown-menu

ModeToggle组件代码请查看

reference/dark-mode.md

。

Critical Rules (MUST FOLLOW)

核心规则（必须遵守）

✅ Always Do:

✅ 必须执行:

Wrap color values with
hsl()
in
:root
and
.dark

css

--background: hsl(0 0% 100%);  /* ✅ Correct */

Use
@theme inline
to map all CSS variables

css

@theme inline {
  --color-background: var(--background);
}

Set
"tailwind.config": ""
in components.json

json

{ "tailwind": { "config": "" } }

Delete
tailwind.config.ts
if it exists
Use
@tailwindcss/vite
plugin (NOT PostCSS)

Use
cn()
for conditional classes

typescript

import { cn } from "@/lib/utils"
<div className={cn("base", isActive && "active")} />

在
:root
和
.dark
中用
hsl()
包裹颜色值

css

--background: hsl(0 0% 100%);  /* ✅ 正确 */

使用
@theme inline
映射所有CSS变量

css

@theme inline {
  --color-background: var(--background);
}

在components.json中设置
"tailwind.config": ""

json

{ "tailwind": { "config": "" } }

如果存在
tailwind.config.ts
请删除
使用
@tailwindcss/vite
插件（不要用PostCSS）

使用
cn()
处理条件类名

typescript

import { cn } from "@/lib/utils"
<div className={cn("base", isActive && "active")} />

❌ Never Do:

❌ 禁止操作:

Put
:root
or
.dark
inside
@layer base

css

/* WRONG */
@layer base {
  :root { --background: hsl(...); }
}

Use
.dark { @theme { } }
pattern

css

/* WRONG - v4 doesn't support nested @theme */
.dark {
  @theme {
    --color-primary: hsl(...);
  }
}

Double-wrap colors

css

/* WRONG */
body {
  background-color: hsl(var(--background));
}

Use
tailwind.config.ts
for theme colors

typescript

/* WRONG - v4 ignores this */
export default {
  theme: {
    extend: {
      colors: { primary: 'hsl(var(--primary))' }
    }
  }
}

Use
@apply
directive (deprecated in v4)

Use
dark:
variants for semantic colors

tsx

/* WRONG */
<div className="bg-primary dark:bg-primary-dark" />

/* CORRECT */
<div className="bg-primary" />

将
:root
或
.dark
放在
@layer base
内部

css

/* 错误 */
@layer base {
  :root { --background: hsl(...); }
}

使用
.dark { @theme { } }
模式

css

/* 错误 - v4不支持嵌套@theme */
.dark {
  @theme {
    --color-primary: hsl(...);
  }
}

双层包裹颜色

css

/* 错误 */
body {
  background-color: hsl(var(--background));
}

使用
tailwind.config.ts
定义主题颜色

typescript

/* 错误 - v4会忽略该配置 */
export default {
  theme: {
    extend: {
      colors: { primary: 'hsl(var(--primary))' }
    }
  }
}

使用
@apply
指令（v4中已废弃）

语义化颜色使用
dark:
前缀

tsx

/* 错误 */
<div className="bg-primary dark:bg-primary-dark" />

/* 正确 */
<div className="bg-primary" />

Semantic Color Tokens

语义化颜色Token

Always use semantic names for colors:

css

:root {
  --destructive: hsl(0 84.2% 60.2%);        /* Red - errors, critical */
  --success: hsl(142.1 76.2% 36.3%);        /* Green - success states */
  --warning: hsl(38 92% 50%);               /* Yellow - warnings */
  --info: hsl(221.2 83.2% 53.3%);           /* Blue - info, primary */
}

Usage:

tsx

<div className="bg-destructive text-destructive-foreground">Critical</div>
<div className="bg-success text-success-foreground">Success</div>
<div className="bg-warning text-warning-foreground">Warning</div>
<div className="bg-info text-info-foreground">Info</div>

颜色始终使用语义化名称:

css

:root {
  --destructive: hsl(0 84.2% 60.2%);        /* 红色 - 错误、临界提示 */
  --success: hsl(142.1 76.2% 36.3%);        /* 绿色 - 成功状态 */
  --warning: hsl(38 92% 50%);               /* 黄色 - 警告 */
  --info: hsl(221.2 83.2% 53.3%);           /* 蓝色 - 提示、主色 */
}

用法:

tsx

<div className="bg-destructive text-destructive-foreground">临界提示</div>
<div className="bg-success text-success-foreground">成功</div>
<div className="bg-warning text-warning-foreground">警告</div>
<div className="bg-info text-info-foreground">提示</div>

Component Best Practices

组件最佳实践

Always use semantic tokens

tsx

<Button variant="destructive">Delete</Button>  /* ✅ */
<Button className="bg-red-600">Delete</Button>  /* ❌ */

Use
cn()
for conditional styling

tsx

import { cn } from "@/lib/utils"

<div className={cn(
  "base-class",
  isActive && "active-class",
  hasError && "error-class"
)} />

Compose shadcn/ui components

tsx

<Dialog>
  <DialogTrigger asChild>
    <Button>Open</Button>
  </DialogTrigger>
  <DialogContent>
    <DialogHeader>
      <DialogTitle>Title</DialogTitle>
    </DialogHeader>
  </DialogContent>
</Dialog>

始终使用语义化token

tsx

<Button variant="destructive">删除</Button>  /* ✅ */
<Button className="bg-red-600">删除</Button>  /* ❌ */

使用
cn()
处理条件样式

tsx

import { cn } from "@/lib/utils"

<div className={cn(
  "base-class",
  isActive && "active-class",
  hasError && "error-class"
)} />

组合使用shadcn/ui组件

tsx

<Dialog>
  <DialogTrigger asChild>
    <Button>打开</Button>
  </DialogTrigger>
  <DialogContent>
    <DialogHeader>
      <DialogTitle>标题</DialogTitle>
    </DialogHeader>
  </DialogContent>
</Dialog>

Animation Packages (Updated Nov 2025)

动画包（2025年11月更新）

shadcn/ui has deprecated

tailwindcss-animate

in favor of

tw-animate-css

for Tailwind v4 compatibility.

✅ DO Install (v4-compatible):

bash

pnpm add -D tw-animate-css

Then add to

src/index.css

css

@import "tailwindcss";
@import "tw-animate-css";

❌ DO NOT Install:

bash

npm install tailwindcss-animate  # Deprecated - v3 only

Why:

tw-animate-css

is the official v4-compatible replacement for animations, required by shadcn/ui components.

Reference: https://ui.shadcn.com/docs/tailwind-v4

shadcn/ui已废弃

tailwindcss-animate

，改用

tw-animate-css

以兼容Tailwind v4。

✅ 请安装（兼容v4）:

bash

pnpm add -D tw-animate-css

然后添加到

src/index.css

css

@import "tailwindcss";
@import "tw-animate-css";

❌ 不要安装:

bash

npm install tailwindcss-animate  # 已废弃 - 仅支持v3

原因:

tw-animate-css

是官方兼容v4的动画替换包，是shadcn/ui组件的必需依赖。

参考: https://ui.shadcn.com/docs/tailwind-v4

Forms Plugin - Reset Form Element Styles

表单插件 - 重置表单元素样式

When to use: Building custom forms without shadcn/ui components, or need consistent cross-browser form styling.

Installation:

bash

pnpm add -D @tailwindcss/forms

Configuration (v4 syntax):

css

/* src/index.css */
@import "tailwindcss";
@plugin "@tailwindcss/forms";

What it does:

Resets browser default form styles
Makes form elements styleable with Tailwind utilities
Fixes cross-browser inconsistencies for inputs, selects, checkboxes, radios

Note: Less critical for shadcn/ui users (they have pre-styled form components), but still useful for basic forms.

适用场景: 不使用shadcn/ui组件构建自定义表单，或是需要跨浏览器一致的表单样式。

安装:

bash

pnpm add -D @tailwindcss/forms

配置（v4语法）:

css

/* src/index.css */
@import "tailwindcss";
@plugin "@tailwindcss/forms";

作用:

重置浏览器默认表单样式
让表单元素可以用Tailwind工具类自定义样式
修复input、select、checkbox、radio的跨浏览器不一致问题

注意: shadcn/ui用户必要性较低（已有预定义样式的表单组件），但对基础表单仍然有用。

Common Plugin Errors

常见插件错误

These errors happen when using v3 syntax in v4 projects:

❌ WRONG (v3 config file syntax):

// tailwind.config.js
module.exports = {
  plugins: [require('@tailwindcss/typography')]
}

❌ WRONG (@import instead of @plugin):

css

@import "@tailwindcss/typography";  /* Doesn't work */

✅ CORRECT (v4 @plugin directive):

css

/* src/index.css */
@import "tailwindcss";
@plugin "@tailwindcss/typography";
@plugin "@tailwindcss/forms";

这些错误是在v4项目中使用v3语法导致的:

❌ 错误（v3配置文件语法）:

// tailwind.config.js
module.exports = {
  plugins: [require('@tailwindcss/typography')]
}

❌ 错误（用@import而非@plugin）:

css

@import "@tailwindcss/typography";  /* 不生效 */

✅ 正确（v4 @plugin指令）:

css

/* src/index.css */
@import "tailwindcss";
@plugin "@tailwindcss/typography";
@plugin "@tailwindcss/forms";

Built-in Features (No Plugin Needed)

内置功能（无需插件）

Container queries are built into Tailwind v4 core - no plugin needed:

tsx

<div className="@container">
  <div className="@md:text-lg">
    Responds to container width, not viewport
  </div>
</div>

❌ Don't install:

@tailwindcss/container-queries

(deprecated, now core feature)

容器查询已内置到Tailwind v4核心 - 无需插件:

tsx

<div className="@container">
  <div className="@md:text-lg">
    响应容器宽度而非视口宽度
  </div>
</div>

❌ 不要安装:

@tailwindcss/container-queries

（已废弃，现在是核心功能）
