}

Color Usage Guidelines​

Primary Actions:

// Use stem-blue for primary CTAs and main interactions
className="bg-stem-blue-500 hover:bg-stem-blue-600 text-white"

Secondary Actions:

// Use white/outlined style for secondary actions
className="bg-white border-2 border-stem-blue-400 text-stem-blue-700"

Success States:

// Use stem-green for positive feedback
className="bg-stem-green-100 text-stem-green-700 border border-stem-green-300"

Warning States:

// Use stem-orange for caution
className="bg-stem-orange-100 text-stem-orange-700 border border-stem-orange-300"

Error States:

// Use stem-red for errors
className="bg-stem-red-100 text-stem-red-700 border border-stem-red-300"

Informational:

// Use stem-teal for informational content
className="bg-stem-teal-100 text-stem-teal-700 border border-stem-teal-300"

Accessibility - Color Contrast​

Minimum Contrast Ratios (WCAG 2.1 AA):

  • Normal text (< 18px): 4.5:1
  • Large text (≥ 18px or 14px bold): 3:1
  • UI components: 3:1

Verified Combinations:

// ✅ PASS - High contrast
'text-slate-900 on bg-white'      // 21:1
'text-white on bg-stem-blue-600'  // 4.5:1
'text-stem-blue-700 on bg-stem-blue-50' // 8.2:1

// ⚠️ REVIEW - Low contrast
'text-slate-400 on bg-white'      // 2.9:1 - Use for disabled only
'text-stem-blue-300 on bg-white'  // 2.1:1 - Avoid

2.2 Typography System​

Font Families​

// /tailwind.config.ts
fontFamily: {
  sans: ['Inter', 'system-ui', '-apple-system', 'sans-serif'],
  display: ['Poppins', 'system-ui', '-apple-system', 'sans-serif'],
  mono: ['JetBrains Mono', 'Menlo', 'Monaco', 'Consolas', 'monospace'],
}

Type Scale​

// Enhanced type scale with semantic naming
fontSize: {
  // Body text
  'xs': ['0.75rem', { lineHeight: '1rem' }],      // 12px
  'sm': ['0.875rem', { lineHeight: '1.25rem' }],  // 14px
  'base': ['1rem', { lineHeight: '1.5rem' }],     // 16px
  'lg': ['1.125rem', { lineHeight: '1.75rem' }],  // 18px
  'xl': ['1.25rem', { lineHeight: '1.75rem' }],   // 20px

  // Headings
  '2xl': ['1.5rem', { lineHeight: '2rem' }],      // 24px - H4
  '3xl': ['1.875rem', { lineHeight: '2.25rem' }], // 30px - H3
  '4xl': ['2.25rem', { lineHeight: '2.5rem' }],   // 36px - H2
  '5xl': ['3rem', { lineHeight: '1' }],           // 48px - H1
  '6xl': ['3.75rem', { lineHeight: '1' }],        // 60px - Hero
  '7xl': ['4.5rem', { lineHeight: '1' }],         // 72px - Display
  '8xl': ['6rem', { lineHeight: '1' }],           // 96px - Giant

  bold: '700',       // Headings
  extrabold: '800',  // Display
  black: '900',      // Ultra display
}

Typography Component​

// /components/ui/Typography.tsx
import { createElement, HTMLAttributes } from 'react'
import clsx from 'clsx'

type TypographyVariant =
  | 'h1' | 'h2' | 'h3' | 'h4' | 'h5' | 'h6'
  | 'body1' | 'body2' | 'caption' | 'overline'
  | 'display1' | 'display2'

interface TypographyProps extends HTMLAttributes<HTMLElement> {
  variant?: TypographyVariant
  component?: keyof JSX.IntrinsicElements
  color?: 'primary' | 'secondary' | 'error' | 'success' | 'warning'
  gradient?: boolean
  weight?: 'normal' | 'medium' | 'semibold' | 'bold'
}

const variantMapping: Record<TypographyVariant, keyof JSX.IntrinsicElements> = {
  h1: 'h1',
  h2: 'h2',
  h3: 'h3',
  h4: 'h4',
  h5: 'h5',
  h6: 'h6',
  body1: 'p',
  body2: 'p',
  caption: 'span',
  overline: 'span',
  display1: 'h1',

  h5: 'text-lg md:text-xl font-display font-semibold',
  h6: 'text-base md:text-lg font-display font-semibold',

  // Body
  body1: 'text-base font-sans',
  body2: 'text-sm font-sans',

  // Utility
  caption: 'text-xs font-sans',
  overline: 'text-xs font-sans uppercase tracking-wider',

  // Display
  display1: 'text-5xl md:text-6xl lg:text-7xl font-display font-bold',
  display2: 'text-4xl md:text-5xl lg:text-6xl font-display font-bold',
}

const colorStyles = {
  primary: 'text-stem-blue-700',
  secondary: 'text-stem-purple-700',
  error: 'text-stem-red-700',
  success: 'text-stem-green-700',
  warning: 'text-stem-orange-700',
}

export function Typography({
  variant = 'body1',
  component,
  color,
  gradient = false,
  weight,
  className,
  children,
  ...props
}: TypographyProps) {
  const Component = component || variantMapping[variant]

  return createElement(
    Component,
    {
      className: clsx(
        variantStyles[variant],
        color && colorStyles[color],
        gradient && 'bg-gradient-to-r from-stem-blue-600 to-stem-purple-600 bg-clip-text text-transparent',
        weight && `font-${weight}`,
        className
      ),
      ...props,
    },
    children
  )
}

Usage:

<Typography variant="h1" gradient>
  Welcome to STEMBlock.ai
</Typography>

<Typography variant="body1" color="primary">
  This is primary colored body text
</Typography>

<Typography variant="caption">
  This is caption text
</Typography>

3. Component Library​

3.1 Component Anatomy​

Every component should follow this structure:

// /components/ui/ComponentName.tsx
import { forwardRef, HTMLAttributes } from 'react'
import clsx from 'clsx'

/**
 * ComponentName - Brief description
 *
 * @example
 * ```tsx
 * <ComponentName variant="primary" size="md">
 *   Content
 * </ComponentName>
 * ```
 */

interface ComponentNameProps extends HTMLAttributes<HTMLDivElement> {
  /** Visual style variant */
  variant?: 'primary' | 'secondary' | 'ghost'

  /** Size of the component */
  size?: 'sm' | 'md' | 'lg'

  /** Whether component takes full width */
  fullWidth?: boolean

  /** Additional custom classes */
  className?: string
}

export const ComponentName = forwardRef<HTMLDivElement, ComponentNameProps>(
  ({
    variant = 'primary',
    size = 'md',
    fullWidth = false,
    className,
    children,
    ...props
  }, ref) => {
    return (
      <div
        ref={ref}

3.2 Component Checklist​

Before marking a component as "complete", ensure:

  • TypeScript interfaces with JSDoc comments
  • Forwarded refs for DOM access
  • Spread props (...props) for extensibility
  • ARIA attributes for accessibility
  • Keyboard navigation support
  • Focus management
  • Loading states (where applicable)
  • Error states (where applicable)
  • Disabled states
  • Responsive design
  • Dark mode support (future)
  • Unit tests
  • Storybook story
  • Documentation

4. Layout Patterns​

4.1 Container System​

// /components/ui/Container.tsx
interface ContainerProps extends HTMLAttributes<HTMLDivElement> {
  size?: 'sm' | 'md' | 'lg' | 'xl' | 'full'
  padding?: boolean
}

export function Container({
  size = 'lg',
  padding = true,
  className,
  children,
  ...props
}: ContainerProps) {
  return (
    <div
      className={clsx(
        'mx-auto',
        {
          'max-w-2xl': size === 'sm',   // 672px
          'max-w-4xl': size === 'md',   // 896px
          'max-w-7xl': size === 'lg',   // 1280px
          'max-w-full': size === 'xl',  // 1536px
        },
        padding && 'px-4 sm:px-6 lg:px-8',
        className
      )}
      {...props}
    >
      {children}
    </div>
  )
}

4.2 Grid System​

// /components/ui/Grid.tsx
interface GridProps extends HTMLAttributes<HTMLDivElement> {
  cols?: 1 | 2 | 3 | 4 | 6 | 12
  gap?: 'none' | 'sm' | 'md' | 'lg' | 'xl'
  responsive?: boolean
}

export function Grid({
  cols = 1,
  gap = 'md',
  responsive = true,
  className,
  children,
  ...props
}: GridProps) {
  return (
    <div
      className={clsx(
        'grid',
        {
          // Columns
          'grid-cols-1': cols === 1 && !responsive,
          'grid-cols-2': cols === 2 && !responsive,
          'grid-cols-3': cols === 3 && !responsive,
          'grid-cols-4': cols === 4 && !responsive,
          'grid-cols-6': cols === 6 && !responsive,
          'grid-cols-12': cols === 12 && !responsive,

          // Responsive columns
          'grid-cols-1 md:grid-cols-2': cols === 2 && responsive,
          'grid-cols-1 md:grid-cols-2 lg:grid-cols-3': cols === 3 && responsive,
          'grid-cols-1 sm:grid-cols-2 lg:grid-cols-4': cols === 4 && responsive,
          'grid-cols-2 md:grid-cols-3 lg:grid-cols-6': cols === 6 && responsive,

          // Gap
          'gap-2': gap === 'sm',
          'gap-4': gap === 'md',
          'gap-6': gap === 'lg',
          'gap-8': gap === 'xl',
        },
        className
      )}
      {...props}
    >
      {children}
    </div>
  )
}

4.3 Stack Layout​

// /components/ui/Stack.tsx
interface StackProps extends HTMLAttributes<HTMLDivElement> {
  direction?: 'vertical' | 'horizontal'
  spacing?: 'none' | 'xs' | 'sm' | 'md' | 'lg' | 'xl'
  align?: 'start' | 'center' | 'end' | 'stretch'
  justify?: 'start' | 'center' | 'end' | 'between' | 'around'
  wrap?: boolean
}

export function Stack({
  direction = 'vertical',
  spacing = 'md',
  align = 'stretch',
  justify = 'start',
  wrap = false,
  className,
  children,
  ...props
}: StackProps) {
  return (
    <div
      className={clsx(
        'flex',
        {
          'flex-col': direction === 'vertical',
          'flex-row': direction === 'horizontal',

          // Spacing
          'space-y-0': spacing === 'none' && direction === 'vertical',
          'space-y-1': spacing === 'xs' && direction === 'vertical',
          'space-y-2': spacing === 'sm' && direction === 'vertical',
          'space-y-4': spacing === 'md' && direction === 'vertical',
          'space-y-6': spacing === 'lg' && direction === 'vertical',
          'space-y-8': spacing === 'xl' && direction === 'vertical',

          'space-x-0': spacing === 'none' && direction === 'horizontal',
          'space-x-1': spacing === 'xs' && direction === 'horizontal',
          'space-x-2': spacing === 'sm' && direction === 'horizontal',
          'space-x-4': spacing === 'md' && direction === 'horizontal',
          'space-x-6': spacing === 'lg' && direction === 'horizontal',
          'space-x-8': spacing === 'xl' && direction === 'horizontal',

          // Alignment
          'items-start': align === 'start',
          'items-center': align === 'center',
          'items-end': align === 'end',
          'items-stretch': align === 'stretch',

          // Justification
          'justify-start': justify === 'start',
          'justify-center': justify === 'center',
          'justify-end': justify === 'end',
          'justify-between': justify === 'between',
          'justify-around': justify === 'around',

          // Wrap
          'flex-wrap': wrap,
        },
        className
      )}
      {...props}
    >
      {children}
    </div>
  )
}

5. Design System Governance​

5.1 Contributing Guidelines​

Before adding a new component:

  1. Check if an existing component can be extended
  2. Discuss with team in design review
  3. Create Figma designs first
  4. Get approval from design lead
  5. Follow component anatomy guidelines
  6. Add to Storybook
  7. Update documentation

Before modifying an existing component:

  1. Check component usage across codebase
  2. Consider backward compatibility
  3. Add deprecation warnings if breaking changes
  4. Update all instances
  5. Update Storybook stories
  6. Update documentation

5.2 Version Control​

// /components/ui/version.ts
export const DESIGN_SYSTEM_VERSION = '1.0.0'

export const CHANGELOG = {
  '1.0.0': {
    date: '2025-12-13',
    changes: [
      'Initial design system release',
      'Core components: Button, Input, Card, Badge',
      'Design tokens: Colors, typography, spacing',
    ],
  },
}

Summary​

This design system provides:

  • ✅ Comprehensive design tokens
  • ✅ Scalable component library
  • ✅ Clear usage guidelines
  • ✅ Accessibility standards
  • ✅ Governance processes

Next Steps:

  1. Implement remaining components
  2. Create Figma component library
  3. Build Storybook documentation
  4. Conduct accessibility audit
  5. Establish design review process
