}
```

## Common Issues & Troubleshooting

### Issue: Sidebar not toggling on mobile

Press F12 → Console tab → Look for red errors
```

### Issue: Dark theme not applying
**Solution:** Clear Xibo cache and browser cache:
1. **Xibo:** Settings → Maintenance → Purge Cache
2. **Browser:** Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac)

### Issue: Images in media grid not showing
**Solution:** Verify image URLs are accessible. Check:
1. File permissions (644 for files, 755 for directories)
2. Image format is supported (JPEG, PNG, GIF, WebP)

### Issue: Search bar styling broken
**Solution:** Ensure `override.css` is fully loaded. Check:
1. CSS file size: should be ~8-10 KB
2. No CSS parse errors in DevTools (F12 → Console)

## Xibo CMS Integration Notes

### Theme Hooks (Twig Blocks)

The theme extends `base.twig` and overrides:

- `{% block head %}` - Link to custom CSS
- `{% block htmlTag %}` - Dark mode attribute
- `{% block body %}` - Custom shell structure
- `{% block header %}` - Topbar
- `{% block content %}` - Main content area
- `{% block footer %}` - Footer
- `{% block scripts %}` - Include theme.js

### Available Twig Variables

In views, you can access:

```twig
{{ baseUrl }}              # Base URL of Xibo CMS
{{ app_name }}             # Application name (from config.php)
{{ user.username }}        # Current user's login
{{ currentDate }}          # Current date/time
{{ pageTitle }}            # Page title (from view)
{{ pageSubtitle }}         # Optional page subtitle
```

### CSS Class Conventions

Custom classes follow BEM naming:

```
.ots-<component>          # Root component
.ots-<component>__item    # Child element
.ots-<component>--active  # Modifier
```
