Overview

A design system is a structured set of components, guidelines, and principles that ensure consistency, accelerate development, and improve product quality.

When to Use

• Multiple product interfaces or teams
• Scaling design consistency
• Reducing redundant component development
• Improving design-to-dev handoff
• Creating shared language across teams
• Building reusable components
• Documenting design standards

Quick Start

Minimal working example:

Design System Structure:

Foundation Layer:
  Typography:
    - Typefaces (Roboto, Inter)
    - Font sizes (scale: 12, 14, 16, 20, 28, 36, 48)
    - Font weights (Regular, Medium, Bold)
    - Line heights and letter spacing

Colors:
  - Primary brand color (#2196F3)
  - Secondary colors
  - Neutral palette (grays)
  - Semantic colors (success, error, warning)
  - Dark mode variants

Spacing:
  - Base unit: 4px
  - Scale: 4, 8, 12, 16, 24, 32, 48, 64px
  - Apply consistently across UI

Shadows & Elevation:
  - Elevation 0 (flat)
  - Elevation 1, 2, 4, 8, 16 (increasing depth)
  - Used for modals, cards, overlays
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Start with essential components
• Document every component thoroughly
• Include code examples
• Test components across browsers
• Include accessibility guidance
• Version the design system
• Have clear governance
• Communicate updates proactively
• Gather feedback from users
• Maintain incrementally

❌ DON'T

• Create too many components initially
• Skip documentation
• Ignore accessibility
• Make breaking changes without migration path
• Allow inconsistent implementations
• Ignore user feedback
• Let design system stagnate
• Create components without proven need
• Make components too prescriptive
• Ignore performance impact
