Mockup to Code Skill

Mockup to Code Skill

Convert UI mockups, screenshots, and designs into production-ready code.

When to Use

• Converting Figma/​Sketch mockups to React/​Vue/​HTML
• Implementing pixel-perfect designs
• Building component libraries from design systems
• Rapid prototyping from wireframes

Core Workflow

Phase 1: Design Analysis

Analyze this UI mockup and extract:

1. LAYOUT STRUCTURE
   - Grid system (columns, gutters, margins)
   - Component hierarchy
   - Container widths

2. VISUAL SPECIFICATIONS
   - Colors (hex values)
   - Typography (sizes, weights)
   - Spacing (padding, margins, gaps)
   - Border radius, shadows

3. COMPONENTS IDENTIFIED
   - List each distinct component
   - Note variations
   - Identify reusable patterns

4. RESPONSIVE CONSIDERATIONS
   - How might this adapt to mobile?
   - Collapsible sections
   - Priority content

Output as structured JSON.

Phase 2: Component Breakdown

## Component: [Name]

**Priority:** High/​Medium/​Low
**Complexity:** Simple/​Medium/​Complex
**Reusability:** One-off/​Reusable/​Design System

**Props Interface:**

- variant: 'primary' | 'secondary'
- size: 'sm' | 'md' | 'lg'
- disabled?: boolean

**Accessibility:**

- Keyboard navigation
- ARIA labels
- Focus management

Phase 3: Implementation

Implement with comparison loop:

Compare mockup vs implementation:

1. What differences do you see?
2. What's missing?
3. Spacing/​sizing adjustments needed?
4. Color accuracy?
5. Typography match?

Prioritize fixes by visual impact.

Technology Patterns

React + Tailwind

Convert to React with Tailwind CSS.

Requirements:
- Functional components with TypeScript
- Tailwind utility classes
- Extract repeated patterns
- Semantic HTML
- Responsive classes (sm:, md:, lg:)

Vue 3

Convert to Vue 3 component.

Requirements:
- Composition API with <script setup>
- Scoped styles
- Props with TypeScript

Plain HTML/​CSS

Convert to semantic HTML and CSS.

Requirements:
- Semantic HTML5 elements
- CSS Grid/​Flexbox layout
- CSS custom properties

Quality Checklist

Visual Fidelity

• Colors match exactly
• Typography matches
• Spacing is consistent
• Border radius matches
• Shadows correct

Responsiveness

• Desktop layout matches
• Tablet works
• Mobile is usable
• No horizontal scroll

Interactions

• Hover states
• Focus states
• Transitions smooth

Code Quality

• Properly typed
• Sensible defaults
• Uses tokens (no hardcoded values)
• Accessible markup

Storage

Save implementations to .opencode/​memory/​design/​implementations/
