# 8-Box Single Line Display Fix

## Problem Statement
The 8 customization boxes were wrapping to multiple rows on smaller screens, making it difficult for mobile users to see and use all boxes effectively.

## Solution Implemented
Changed the layout to **ALWAYS display all 8 boxes in a single horizontal line** with horizontal scrolling enabled on smaller screens.

---

## ✅ Changes Made

### 1. **CSS Layout Changes**
**File:** `resources/views/student/bracelet-customize.blade.php`

#### Base Layout (Desktop):
```css
.boxes-display {
    display: flex;
    gap: 0.5rem;
    justify-content: flex-start;
    flex-wrap: nowrap; /* NEVER WRAP */
    overflow-x: auto; /* Enable horizontal scroll */
    -webkit-overflow-scrolling: touch; /* Smooth iOS scrolling */
    scroll-behavior: smooth;
}

.box-item {
    min-width: 70px;
    width: 70px;
    height: 70px;
    flex-shrink: 0; /* NEVER SHRINK */
}
```

#### Mobile Breakpoints:
- **Desktop:** 70x70px boxes
- **Tablet (≤768px):** 60x60px boxes
- **Mobile (≤480px):** 52x52px boxes
- **Extra Small (≤375px):** 48x48px boxes

### 2. **Custom Scrollbar Styling**
Added styled scrollbar for better UX:
```css
.boxes-display::-webkit-scrollbar {
    height: 8px;
}

.boxes-display::-webkit-scrollbar-thumb {
    background: #B5702F; /* Brand color */
    border-radius: 4px;
}
```

### 3. **Scroll Hint Indicator**
Added a visual hint that appears on mobile to indicate scrollability:
```html
<div id="scrollHint">
    ← Swipe to see all boxes →
</div>
```

**JavaScript Logic:**
- Shows hint only on mobile when boxes overflow
- Automatically hides after first scroll
- Rechecks on window resize
