        gap: 10px;
    }

        text-align: center;
    }

        order: -1;
    }
}
```

Modify spacing and layout by adjusting CSS properties:

```css
.letterhead {
    margin-bottom: 25px; /* Adjust spacing */

## Troubleshooting

### Logo Issues

#### 1. Logo Not Displaying
**Symptoms:** Logo doesn't appear in reports
**Causes:**

   ```bash
   php artisan logo:check --fix
   ```

2. **Check database value:**
   ```sql
   SELECT company_logo FROM configs ORDER BY id DESC LIMIT 1;
   ```

3. **Verify storage configuration:**

   // In tinker or test
   Storage::disk('public')->exists('logos/your-logo.png');
   ```

#### 3. Logo Display Issues
**Symptoms:** Logo appears but looks wrong
**Solutions:**
- **Wrong size:** Adjust CSS max-width/max-height

@php
$info = \App\Config::latest()->first();
dd($info); // This will show all available data
@endphp
```

### Logo Debugging Command
Use the built-in command to debug logo issues:

```bash
# Check logo configuration
php artisan logo:check

# Check and attempt to fix issues
php artisan logo:check --fix
```

**Command Output Example:**
