When to Use Each Layer
各层级适用场景
Use TailwindCSS Directly When:
直接使用TailwindCSS的场景:
- Building custom layouts and spacing
- Styling static content and containers
- Rapid prototyping without complex interactions
- Non-interactive UI elements
Example scenarios: Hero sections, grid layouts, cards without interaction, text styling
- 构建自定义布局与间距
- 为静态内容与容器设置样式
- 无需复杂交互的快速原型开发
- 非交互式UI元素
示例场景: Hero区域、网格布局、无交互卡片、文本样式
Use Radix UI Primitives When:
使用Radix UI原语的场景:
- Building custom component libraries
- Need accessibility but require custom design
- shadcn/ui doesn't have the component you need
- Full control over component structure required
Example scenarios: Custom date picker, unique navigation pattern, specialized modal behavior
- 构建自定义组件库
- 需要可访问性但需自定义设计
- shadcn/ui没有你需要的组件
- 需要完全控制组件结构
示例场景: 自定义日期选择器、独特导航模式、特殊模态框交互
Use shadcn/ui Components When:
使用shadcn/ui组件的场景:
- Building standard UI components quickly
- Need beautiful defaults with customization options
- Enterprise application development
- Form-heavy applications with validation
Example scenarios: Admin dashboards, CRUD applications, settings pages, data tables
- 快速构建标准UI组件
- 需要美观默认样式且支持自定义
- 企业级应用开发
- 表单密集型应用(带验证)
示例场景: 管理后台、CRUD应用、设置页面、数据表格
Critical Design Principles
关键设计原则
1. Progressive Enhancement
1. 渐进式增强
Start simple, enhance as needed:
- Tailwind utilities for basic styling
- Add Radix primitives for interaction
- Use shadcn/ui for complete solutions
- Customize components in your codebase
从简单开始,按需增强:
- 使用Tailwind工具类实现基础样式
- 添加Radix原语实现交互
- 使用shadcn/ui获得完整解决方案
- 在你的代码库中自定义组件
2. Composition Over Complexity
2. 组合优于复杂
Build complex UIs from simple, reusable components:
- Small, focused components (single responsibility)
- Compose primitives rather than creating monoliths
- Leverage component slots and children patterns
通过简单、可复用组件构建复杂UI:
- 小巧、聚焦的组件(单一职责)
- 组合原语而非创建单体组件
- 利用组件插槽与子元素模式
3. Accessibility First
3. 可访问性优先
Radix UI handles accessibility automatically:
- ARIA attributes applied correctly
- Keyboard navigation built-in
- Focus management and trapping
- Screen reader compatibility
Never override accessibility features - enhance them.
Radix UI自动处理可访问性:
- 正确应用ARIA属性
- 内置键盘导航
- 自动焦点管理与捕获
- 屏幕阅读器兼容
永远不要覆盖可访问性功能 - 而是增强它们。
4. Design Token Consistency
4. 设计令牌一致性
Use Tailwind's design system consistently:
- Stick to spacing scale (4, 8, 16, 24px)
- Use color palette (50-950 shades)
- Apply typography scale systematically
- Avoid arbitrary values unless necessary
始终遵循Tailwind的设计系统:
- 坚持使用间距比例(4、8、16、24px)
- 使用调色板(50-950色调)
- 系统地应用排版比例
- 除非必要,避免使用任意值
5. Mobile-First Responsive
5. 移动端优先响应式
Always design mobile-first, scale up:
- Base styles for mobile
- Use breakpoints (sm, md, lg, xl, 2xl) to enhance
- Test on actual devices, not just browser resize
始终从移动端开始设计,逐步扩展:
- 为移动端设置基础样式
- 使用断点(sm、md、lg、xl、2xl)进行增强
- 在真实设备上测试,而非仅靠浏览器缩放
Setup Strategy
搭建策略
Installation Order
安装顺序
- TailwindCSS - Foundation
- shadcn/ui CLI - Includes Radix dependencies
- Add components - Install only what you need
- Configure theme - CSS variables + Tailwind config
- Setup dark mode - Theme provider + toggle
- TailwindCSS - 基础
- shadcn/ui CLI - 包含Radix依赖
- 添加组件 - 仅安装你需要的组件
- 配置主题 - CSS变量 + Tailwind配置
- 设置深色模式 - 主题提供者 + 切换器
Configuration Best Practices
配置最佳实践
Tailwind Config:
- Use paths correctly (scan all component files)
content - Extend theme with CSS variables, not hardcoded values
- Enable dark mode with strategy
class - Install plugin
tailwindcss-animate
CSS Variables (Three-Tier System):
css
:root {
/* Tier 1: Primitives (immutable) */
--gray-50: 250 250 250;
--gray-900: 24 24 27;
--blue-500: oklch(0.55 0.22 264);
/* Tier 2: Semantics (theme-aware) */
--background: var(--gray-50);
--foreground: var(--gray-900);
--primary: var(--blue-500);
/* Tier 3: Components */
--button-height: 2.5rem;
--card-padding: 1.5rem;
}
.dark {
/* Only semantic tokens change */
--background: var(--gray-900);
--foreground: var(--gray-50);
}Color Space Recommendation:
- Modern: Use OKLCH for perceptual uniformity
- Legacy support: Use HSL with fallbacks
- Avoid: RGB/HEX for design tokens (not human-readable)
Token Storage:
- Store in JSON for platform-agnostic distribution
- Transform to CSS variables, Swift, XML using Style Dictionary
- Version control tokens separately from component code
Path Aliases:
- Configure and
@/componentsin tsconfig@/lib - Ensure consistency between Next.js and TypeScript configs
- Use aliases in imports for cleaner code
Tailwind配置:
- 正确使用路径(扫描所有组件文件)
content - 使用CSS变量扩展主题,而非硬编码值
- 启用策略的深色模式
class - 安装插件
tailwindcss-animate
CSS变量(三级系统):
css
:root {
/* Tier 1: Primitives (immutable) */
--gray-50: 250 250 250;
--gray-900: 24 24 27;
--blue-500: oklch(0.55 0.22 264);
/* Tier 2: Semantics (theme-aware) */
--background: var(--gray-50);
--foreground: var(--gray-900);
--primary: var(--blue-500);
/* Tier 3: Components */
--button-height: 2.5rem;
--card-padding: 1.5rem;
}
.dark {
/* Only semantic tokens change */
--background: var(--gray-900);
--foreground: var(--gray-50);
}色彩空间推荐:
- 现代方案:使用OKLCH实现感知均匀性
- 兼容旧系统:使用HSL并提供降级方案
- 避免:为设计令牌使用RGB/HEX(不易读)
令牌存储:
- 存储在JSON中以实现跨平台分发
- 使用Style Dictionary转换为CSS变量、Swift、XML
- 将令牌与组件代码分开进行版本控制
路径别名:
- 在tsconfig中配置和
@/components@/lib - 确保Next.js与TypeScript配置一致
- 在导入中使用别名以简化代码
Integration Patterns
集成模式
Pattern 1: shadcn/ui + Custom Tailwind
模式1:shadcn/ui + 自定义Tailwind
Use shadcn/ui components as base, customize with Tailwind classes:
- Apply custom spacing, colors via className prop
- Override default styles with Tailwind utilities
- Maintain component accessibility
以shadcn/ui组件为基础,使用Tailwind类进行自定义:
- 通过className属性应用自定义间距、颜色
- 使用Tailwind工具类覆盖默认样式
- 保持组件可访问性
Pattern 2: Radix Primitives + Tailwind
模式2:Radix原语 + Tailwind
Build custom components from scratch:
- Use Radix for behavior (Dialog, Dropdown, etc.)
- Style completely with Tailwind utilities
- Full control over structure and appearance
从零开始构建自定义组件:
- 使用Radix实现交互(Dialog、Dropdown等)
- 完全使用Tailwind工具类设置样式
- 完全控制结构与外观
Pattern 3: Hybrid Approach
模式3:混合方案
Modify shadcn/ui components in your codebase:
- Edit component files in
components/ui/ - Add new variants, sizes, or styles
- Maintain type safety with CVA (Class Variance Authority)
在你的代码库中修改shadcn/ui组件:
- 编辑中的组件文件
components/ui/ - 添加新变体、尺寸或样式
- 使用CVA(Class Variance Authority)保持类型安全
Pattern 4: Component Composition
模式4:组件组合
Combine multiple primitives for complex UIs:
- Popover + Select for searchable dropdown
- Dialog + Form for modal forms
- Tabs + Cards for multi-section interfaces
组合多个原语构建复杂UI:
- Popover + Select 实现可搜索下拉框
- Dialog + Form 实现模态表单
- Tabs + Cards 实现多区域界面
Design Token Architecture
设计令牌架构
Use three-tier token system for scalable, maintainable design systems:
- Tier 1 (Primitive): Raw values (,
gray-50)spacing-4 - Tier 2 (Semantic): Purpose-driven (,
background-primary)text-error - Tier 3 (Component): Component-specific (,
button-height)card-padding
Modern Color: Use OKLCH color space for perceptual uniformity and better accessibility calculations.
📖 See DESIGN_TOKENS.md for:
- Complete three-tier token system implementation
- OKLCH color space guide and examples
- Token naming conventions and best practices
- CSS variable configuration
- Multi-theme support patterns
使用三级令牌系统构建可扩展、可维护的设计系统:
- 第一层(基础):原始值(、
gray-50)spacing-4 - 第二层(语义):基于用途的命名(、
background-primary)text-error - 第三层(组件):组件特定值(、
button-height)card-padding
现代色彩方案: 使用OKLCH色彩空间实现感知均匀性,便于更可靠、可预测的对比度计算。
