Design System Creation

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

Instructions

1. Design System Components

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

            'name': component.name,
            'description': component.description,
            'usage': component.when_to_use,
            'anatomy': {
                'elements': component.sub_elements,
                'diagram': 'Show with labels'
            },
            'properties': {
                'size': ['Small', 'Medium', 'Large'],
                'variant': component.variants,
                'state': ['Default', 'Hover', 'Focus', 'Disabled'],
                'disabled': True/False,
                'required': True/False
            },
            'code_examples': [
                'React example',
                'CSS example',
                'HTML example'
            ],
            'accessibility': {
                'aria_roles': component.aria_roles,
                'keyboard_support': component.keyboard_behavior,
                'screen_reader': component.sr_text
            },
            'do_dont': {
                'do': ['Guideline 1', 'Guideline 2'],
                'dont': ['Guideline 1', 'Guideline 2']
            }
        }

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

Design System Tips

• Start with colors, typography, spacing
• Build most-used components first
• Use Storybook or similar for documentation
• Version using semantic versioning
• Establish clear contribution process
