Design System

Design System Initiative

Creating a unified design system was a strategic initiative to improve consistency, accelerate development, and establish a shared design language across our organization. This project has become the foundation for all new product development.

Component Library

The design system includes over 50 carefully crafted components, each designed with flexibility and accessibility at their core.

Base Components

• Button: Multiple variants (primary, secondary, danger) with loading states
• Input: Text, number, email, password with validation indicators
• Select: Searchable dropdown with multi-select support
• Checkbox & Radio: Accessible form controls with custom styling
• Card: Flexible container with header, body, and footer
• Modal: Accessible dialog with animation and focus management

Data Components

• Table: Sortable, filterable data tables with pagination
• Pagination: Navigation component for large datasets
• Skeleton: Loading placeholders with animated effect
• Badge: Status and category indicators

Layout Components

• Grid: Responsive CSS grid layout system
• Flex: Flexible box layout utility component
• Container: Responsive max-width container
• Stack: Spacing utility for arranging content

Design Tokens

Comprehensive design tokens ensure consistency across all products.

  colors: {
    primary: '#0066CC',
    secondary: '#FF6B6B',
    success: '#10B981',
    warning: '#F59E0B',

    heading1: { fontSize: '2rem', fontWeight: '700' },
    heading2: { fontSize: '1.5rem', fontWeight: '600' },
    body: { fontSize: '1rem', fontWeight: '400' },
    small: { fontSize: '0.875rem', fontWeight: '400' },
  },
  spacing: {
    xs: '4px',
    sm: '8px',
    md: '16px',
    lg: '24px',
    xl: '32px',
  },
  borderRadius: {
    sm: '4px',
    md: '8px',
    lg: '16px',
    full: '9999px',
  },
};

Accessibility (WCAG 2.1 AA)

Every component meets WCAG 2.1 AA compliance standards:

• Keyboard Navigation: Full keyboard support for all interactive components
• Color Contrast: Minimum 4.5:1 contrast ratio for text
• Screen Readers: Proper ARIA labels and semantic HTML
• Focus Management: Visible focus indicators and logical tab order
• Motion: Respects prefers-reduced-motion preference

Documentation & Storybook

We use Storybook to showcase components with:

• Interactive component previews
• Live documentation
• Accessibility audits for each component
• Code examples and best practices
• Design system guidelines
