# CSS Generation Skill

Generate CSS, Tailwind, and styled-components code from design style selections.

## Overview

This skill provides tools and templates for converting design tokens and style selections into production-ready CSS, Tailwind configurations, and styled-components theme objects.

## CSS Variables Generation from Design Tokens

### Design Token Structure

```typescript
interface DesignTokens {
  colors: ColorTokens;
  spacing: SpacingTokens;
  typography: TypographyTokens;
  shadows: ShadowTokens;
  borders: BorderTokens;
  effects: EffectTokens;
}

interface ColorTokens {
  primary: ColorScale;
  secondary: ColorScale;
  neutral: ColorScale;
  success: ColorScale;
  warning: ColorScale;
  error: ColorScale;
  info: ColorScale;
}

interface ColorScale {
  50: string;
  100: string;
  200: string;
  300: string;
  400: string;
  500: string;  // Base color
  600: string;
  700: string;
  800: string;
  900: string;
}
```

### CSS Variables Template

### Dark Theme

**styles/themes/dark.ts:**
```typescript
import { Theme } from '../theme';
import { lightTheme } from './light';

export const darkTheme: Theme = {
  ...lightTheme,
  colors: {
    ...lightTheme.colors,
    text: {
      primary: '#fafafa',
      secondary: '#a3a3a3',
      disabled: '#525252',
      inverse: '#171717',
    },
    background: {
      primary: '#0a0a0a',
      secondary: '#171717',
      tertiary: '#262626',
      inverse: '#ffffff',
    },
    border: {
      default: '#404040',
      hover: '#525252',
      focus: '#3b82f6',
    },
  },
};
```

### Usage with styled-components

**components/Button.tsx:**
```typescript
import styled from 'styled-components';

export const Button = styled.button<{ variant?: 'primary' | 'secondary' }>`
  padding: ${({ theme }) => `${theme.spacing[2]} ${theme.spacing[4]}`};
  font-family: ${({ theme }) => theme.typography.fontFamily.sans};
  font-size: ${({ theme }) => theme.typography.fontSize.base};
  font-weight: ${({ theme }) => theme.typography.fontWeight.medium};
  border-radius: ${({ theme }) => theme.borderRadius.md};
  border: none;
  cursor: pointer;
  transition: all ${({ theme }) => theme.transitions.duration.base}
    ${({ theme }) => theme.transitions.easing.inOut};

  background-color: ${({ theme, variant = 'primary' }) =>
    variant === 'primary'
      ? theme.colors.primary[500]
      : theme.colors.secondary[500]};

  color: ${({ theme }) => theme.colors.text.inverse};

  box-shadow: ${({ theme }) => theme.shadows.sm};

  &:hover {
    background-color: ${({ theme, variant = 'primary' }) =>
      variant === 'primary'
        ? theme.colors.primary[600]
        : theme.colors.secondary[600]};
    box-shadow: ${({ theme }) => theme.shadows.md};
  }

  &:active {
    transform: translateY(1px);
  }

  &:focus-visible {
    outline: 2px solid ${({ theme }) => theme.colors.border.focus};
    outline-offset: 2px;
  }

  &:disabled {
    background-color: ${({ theme }) => theme.colors.neutral[300]};
    color: ${({ theme }) => theme.colors.text.disabled};
    cursor: not-allowed;
    box-shadow: none;
  }
`;
```

## Format Conversion

### CSS to Tailwind

```typescript
// Convert CSS variables to Tailwind classes
function cssToTailwind(cssProperties: Record<string, string>): string {
  const mapping: Record<string, (value: string) => string> = {
    'background-color': (val) => {
      if (val.startsWith('var(--color-')) {
        const color = val.match(/--color-(\w+)-(\d+)/);
        if (color) return `bg-${color[1]}-${color[2]}`;
      }
      return '';
    },
    'color': (val) => {
      if (val.startsWith('var(--color-')) {
        const color = val.match(/--color-(\w+)-(\d+)/);
        if (color) return `text-${color[1]}-${color[2]}`;
      }
      return '';
    },
    'padding': (val) => {
      if (val.startsWith('var(--spacing-')) {
        const spacing = val.match(/--spacing-(\w+)/);
        if (spacing) return `p-${spacing[1]}`;
      }
      return '';
    },
    // Add more mappings...
  };

  return Object.entries(cssProperties)
    .map(([prop, value]) => mapping[prop]?.(value) || '')
    .filter(Boolean)
    .join(' ');
}
```

### Tailwind to styled-components

```typescript
// Convert Tailwind config to styled-components theme
function tailwindToStyledTheme(tailwindConfig: any): Theme {
  return {
    colors: tailwindConfig.theme.extend.colors,
    spacing: tailwindConfig.theme.extend.spacing,
    typography: {
      fontFamily: tailwindConfig.theme.extend.fontFamily,
      fontSize: tailwindConfig.theme.extend.fontSize,
      fontWeight: {
        thin: 100,
        // ... map all weights
      },
      lineHeight: {
        none: 1,
        // ... map all line heights
      },
    },
    shadows: tailwindConfig.theme.extend.boxShadow,
    borderRadius: tailwindConfig.theme.extend.borderRadius,
    transitions: {
      duration: {
        fast: '150ms',
        // ... map durations
      },
      easing: {
        linear: 'linear',
        // ... map easings
      },
    },
  };
}
```

## Dark Mode Variant Generation

### Automatic Dark Mode Classes

```typescript
// Generate dark mode variants for CSS
function generateDarkModeVariants(baseColors: ColorTokens): string {
  return `
    :root {
      ${Object.entries(baseColors).map(([name, scale]) =>
        Object.entries(scale).map(([weight, color]) =>
          `--color-${name}-${weight}: ${color};`
        ).join('\n')
      ).join('\n')}
    }

    [data-theme="dark"] {
      /* Invert color scales for dark mode */
      ${Object.entries(baseColors).map(([name, scale]) =>
        Object.entries(scale).map(([weight, _]) => {
          const invertedWeight = 1000 - parseInt(weight);
          return `--color-${name}-${weight}: var(--color-${name}-${invertedWeight});`;
        }).join('\n')
      ).join('\n')}
    }
  `;
}
```

## Style-Specific Generators

### Glassmorphism Generator

```typescript
export function generateGlassmorphismCSS(options: {
  blur?: number;
  opacity?: number;
  color?: string;
  borderOpacity?: number;
}) {
  const {
    blur = 10,
    opacity = 0.1,
    color = '#ffffff',
    borderOpacity = 0.2,
  } = options;

  return `
    background: rgba(${hexToRgb(color)}, ${opacity});
    backdrop-filter: blur(${blur}px);
    -webkit-backdrop-filter: blur(${blur}px);
    border: 1px solid rgba(${hexToRgb(color)}, ${borderOpacity});
    box-shadow: 0 8px 32px 0 rgba(31, 38, 135, 0.37);
  `;
}
```

### Neumorphism Generator

```typescript
export function generateNeumorphismCSS(options: {
  lightColor?: string;
  darkColor?: string;
  distance?: number;
  intensity?: number;
  blur?: number;
}) {
  const {
    lightColor = '#ffffff',
    darkColor = '#d1d9e6',
    distance = 8,
    intensity = 1,
    blur = 16,
  } = options;

  return `
    background: #e0e5ec;
    box-shadow:
      ${distance}px ${distance}px ${blur}px ${darkColor},
      -${distance}px -${distance}px ${blur}px ${lightColor};
  `;
}
```

### Neo-Brutalism Generator

```typescript
export function generateNeoBrutalismCSS(options: {
  bgColor?: string;
  borderColor?: string;
  borderWidth?: number;
  shadowOffset?: number;
}) {
  const {
    bgColor = '#ffff00',
    borderColor = '#000000',
    borderWidth = 4,
    shadowOffset = 8,
  } = options;

  return `
    background-color: ${bgColor};
    border: ${borderWidth}px solid ${borderColor};
    box-shadow: ${shadowOffset}px ${shadowOffset}px 0px ${borderColor};
  `;
}
```

## Utility Functions

```typescript
function hexToRgb(hex: string): string {
  const result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex);
  return result
    ? `${parseInt(result[1], 16)}, ${parseInt(result[2], 16)}, ${parseInt(result[3], 16)}`
    : '0, 0, 0';
}

function rgbToHex(r: number, g: number, b: number): string {
  return '#' + [r, g, b].map(x => {
    const hex = x.toString(16);
    return hex.length === 1 ? '0' + hex : hex;
  }).join('');
}

function lighten(color: string, amount: number): string {
  // Implementation
  return color;
}

function darken(color: string, amount: number): string {
  // Implementation
  return color;
}
```
