# Phase 3: Mockup Creation

> Design before you code

## Purpose

Create visual prototypes to validate UI/UX before implementation.

## Deliverables

### 1. Wireframes

Low-fidelity layouts showing structure:

```
┌─────────────────────────────────┐
│ [Logo]              [Nav] [User]│
├─────────────────────────────────┤
│                                 │
│   ┌─────────┐  ┌─────────┐     │
│   │ Card 1  │  │ Card 2  │     │
│   └─────────┘  └─────────┘     │
│                                 │
│   ┌─────────┐  ┌─────────┐     │
│   │ Card 3  │  │ Card 4  │     │
│   └─────────┘  └─────────┘     │
│                                 │
└─────────────────────────────────┘
```

### 2. Component Mockups

HTML/CSS prototypes:

```html
<!-- components/mockups/card.html -->
<div class="card">
  <img src="placeholder.jpg" alt="">
  <h3>Title</h3>
  <p>Description text here</p>
  <button>Action</button>
</div>
```

### 3. User Flows

Document user journeys:

```
Home → Browse Products → View Product → Add to Cart → Checkout → Payment → Confirmation
```

## Tools

- HTML/CSS prototypes (recommended)
- Figma exports
- ASCII diagrams

## Output

Save to: `docs/02-design/mockups/`

## Next Phase

After completion: `/phase-4-api` (Dynamic/Enterprise) or `/phase-6-ui-integration` (Starter)
