npm install keypix-ui
```

### 2. Import and use components

```tsx
import { Button, Input, Card, ThemeProvider } from 'keypix-ui'

function App() {
  return (
    <ThemeProvider>
      <div className="keypix-p-8">
        <Card>
          <CardHeader>
            <CardTitle>Welcome to Keypix UI</CardTitle>
          </CardHeader>
          <CardContent>
            <Input placeholder="Enter your name" />
            <Button>Get Started</Button>
          </CardContent>
        </Card>
      </div>
    </ThemeProvider>
  )
}
```

**That's it!** 🎉 No configuration needed. Styles are automatically injected.

## 🎯 Auto-Styling

Keypix UI automatically applies global styles when imported, including:

```css
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  -webkit-tap-highlight-color: transparent;
  font-family: 'Inter', sans-serif;
}

*:focus,
*:active {
  outline: none;
}

html,
body {
  height: 100%;
}
```

These styles provide a clean foundation for your application. The Inter font is automatically loaded from Google Fonts.

      <ThemeToggle />
      {/* Your app content */}
    </ThemeProvider>
  )
}

## 🎨 Customization

### CSS Variables

Keypix UI uses CSS variables for easy customization:

```css
:root {
  --primary: 221.2 83.2% 53.3%;
  --primary-foreground: 210 40% 98%;
  --secondary: 210 40% 96%;
  --secondary-foreground: 222.2 84% 4.9%;
  --background: 0 0% 100%;
  --foreground: 222.2 84% 4.9%;
  --border: 214.3 31.8% 91.4%;
  --radius: 0.5rem;
}

.dark {
  --background: 222.2 84% 4.9%;
  --foreground: 210 40% 98%;
  /* ... other dark theme variables */
}
```

### Custom Theme

```tsx
import { ThemeProvider } from 'keypix-ui'

function App() {
  return (
    <ThemeProvider 
      defaultTheme="dark"
      storageKey="my-app-theme"
    >
      {/* Your app */}
    </ThemeProvider>
  )
}
```

### Component Styling

```tsx
// Using className prop
<Button className="keypix-bg-red-500 hover:keypix-bg-red-600">
  Custom Button
</Button>

// Using CSS variables
<Button style={{ '--primary': '220 13% 91%' }}>
  Custom Primary
</Button>
```

## 📱 Responsive Design

All components are mobile-first and responsive:

```tsx
// Responsive grid
<div className="keypix-grid keypix-grid-cols-1 md:keypix-grid-cols-2 lg:keypix-grid-cols-3 keypix-gap-4">
  <Card>Card 1</Card>
  <Card>Card 2</Card>
  <Card>Card 3</Card>
</div>

// Responsive spacing
<div className="keypix-p-4 md:keypix-p-6 lg:keypix-p-8">
  Content with responsive padding
</div>
```

## ♿ Accessibility

Keypix UI is built with accessibility in mind:

- **WCAG 2.1 AA compliant**
- **Keyboard navigation** support
- **Screen reader** friendly
- **High contrast** mode support
- **Reduced motion** preferences
- **ARIA attributes** on all components

```tsx
// Accessible button with proper labels
<Button 
  aria-label="Download file"
  aria-describedby="download-description"
>
  Download
</Button>
<div id="download-description" className="keypix-sr-only">
  Downloads the current file in PDF format
</div>
```
