## 🔍 Debugging Tips

### Issue: Layout terlihat aneh di mobile
```
✓ Check: Viewport meta tag
✓ Check: CSS media queries
✓ Check: Element widths (should be 100% or responsive units)
✓ Test: Clear cache (Ctrl+Shift+Delete)
```

### Issue: Text terlalu kecil di mobile
```
✓ Solusi: Add font-size to mobile media query
✓ Min font-size: 14px untuk readability
✓ Use rem units: 0.9rem, 1rem, etc
```

### Issue: Button tidak responsive
```
✓ Check: Button width (should be 100% or flex)
✓ Check: Button padding (0.5rem on mobile, 0.75rem on desktop)
✓ Add: touch-action: manipulation; untuk better touch handling
```

### Issue: Gambar terlihat stretched
```
✓ Use: object-fit: cover; atau object-fit: contain;
✓ Use: aspect-ratio: 16 / 9; atau proporsi lain
✓ Alternative: Gunakan max-width dan height auto
```

## ✨ Best Practices

### 1. Mobile-First Development
```
❌ WRONG: Desktop first, then min-width media queries
✅ RIGHT: Mobile first, then min-width media queries
```

### 2. Flexible Units
```
❌ WRONG: width: 300px;
✅ RIGHT: width: 100%; max-width: 300px;
```

### 3. Touch-Friendly
```
❌ WRONG: padding: 2px 4px;
✅ RIGHT: padding: 0.5rem; min-height: 44px;
```

### 4. Image Handling
```
❌ WRONG: <img width="800px" height="600px">
✅ RIGHT: <img class="img-responsive"> 
         with max-width: 100%; height: auto;
```

### 5. Typography
```
❌ WRONG: font-size: 8px;
✅ RIGHT: font-size: 0.9rem; (min 14px on mobile)
```

            gap: 1rem;">
    @foreach($items as $item)
        <div>{{ $item }}</div>
    @endforeach
</div>
```

        <div>{{ $item }}</div>
    @endforeach
</div>

<style>
  @media (min-width: 768px) {
    div { flex-direction: row; }
  }
</style>
```

### Responsive Text
