# UX Design Systems
Build consistent, maintainable design systems with tokens, components, and theming.
## Design Tokens
### CSS Variables
```css
:root {
/* Colors */
--color-primary-50: #eff6ff;
--color-primary-500: #3b82f6;
--color-primary-900: #1e3a8a;
/* Typography */
--font-sans: 'Inter', system-ui, sans-serif;
--font-size-sm: 0.875rem;
--font-size-base: 1rem;
--font-size-lg: 1.125rem;
/* Spacing */
--space-1: 0.25rem;
--space-2: 0.5rem;
--space-4: 1rem;
--space-8: 2rem;
/* Border Radius */
--radius-sm: 0.25rem;
--radius-md: 0.375rem;
--radius-lg: 0.5rem;
--radius-full: 9999px;

/* Shadows */
--shadow-sm: 0 1px 2px 0 rgb(0 0 0 / 0.05);
--shadow-md: 0 4px 6px -1px rgb(0 0 0 / 0.1);
}
```
### TypeScript Token System
```typescript
export const tokens = {
colors: {
primary: {
50: '#eff6ff',
500: '#3b82f6',
900: '#1e3a8a',
},
gray: {
50: '#f9fafb',
500: '#6b7280',
900: '#111827',
},
},
spacing: {
1: '0.25rem',
2: '0.5rem',
4: '1rem',
8: '2rem',
},
fontSize: {
sm: '0.875rem',
base: '1rem',
lg: '1.125rem',
xl: '1.25rem',
},
} as const;
type ColorToken = keyof typeof tokens.colors;
type SpaceToken = keyof typeof tokens.spacing;
```
## Component Patterns
### Button Component
```tsx
import { cva, type VariantProps } from 'class-variance-authority';
const buttonVariants = cva(
'inline-flex items-center justify-center rounded-md font-medium transition-colors focus-visible:outline-none focus-visible:ring-2 disabled:pointer-events-none disabled:opacity-50',
{
variants: {
variant: {
primary: 'bg-primary-500 text-white hover:bg-primary-600',
secondary: 'bg-gray-100 text-gray-900 hover:bg-gray-200',
outline: 'border border-gray-300 bg-transparent hover:bg-gray-50',
ghost: 'hover:bg-gray-100',
destructive: 'bg-red-500 text-white hover:bg-red-600',
},
size: {
sm: 'h-8 px-3 text-sm',
md: 'h-10 px-4 text-base',
lg: 'h-12 px-6 text-lg',
},
},
defaultVariants: {
variant: 'primary',
size: 'md',
},
}
);
interface ButtonProps
extends React.ButtonHTMLAttributes<HTMLButtonElement>,
VariantProps<typeof buttonVariants> {
isLoading?: boolean;
}
export function Button({
className,
variant,
size,
isLoading,
children,
...props
}: ButtonProps) {
return (
<button
className={buttonVariants({ variant, size, className })}
disabled={isLoading}
{...props}
>
{isLoading && <Spinner className="mr-2 h-4 w-4" />}
{children}
</button>
);
}
```
## Dark Mode
### CSS-Based Theme Switching
```css
:root {
--bg-primary: #ffffff;
--text-primary: #111827;
--border-color: #e5e7eb;
}
[data-theme='dark'] {
--bg-primary: #111827;
--text-primary: #f9fafb;
--border-color: #374151;
}
```
### React Theme Provider
```tsx
import { createContext, useContext, useEffect, useState } from 'react';
type Theme = 'light' | 'dark' | 'system';
const ThemeContext = createContext<{
theme: Theme;
setTheme: (theme: Theme) => void;
}>({ theme: 'system', setTheme: () => {} });
export function ThemeProvider({ children }: { children: React.ReactNode }) {
const [theme, setTheme] = useState<Theme>('system');
useEffect(() => {
const root = document.documentElement;
if (theme === 'system') {
const systemTheme = window.matchMedia('(prefers-color-scheme: dark)').matches
? 'dark'
: 'light';
root.setAttribute('data-theme', systemTheme);
} else {
root.setAttribute('data-theme', theme);
}
}, [theme]);
return (
<ThemeContext.Provider value={{ theme, setTheme }}>
{children}
</ThemeContext.Provider>
);
}
export const useTheme = () => useContext(ThemeContext);
```
