## 🐛 Troubleshooting

<details>
<summary><b>Common Issues and Solutions</b></summary>

### Node won't select/move?
**Solution:** Click on the node's title bar or edges, not the HTML content area

### Links not working?
**Solution:** Remember to hold the **Control key** while clicking links

### JavaScript not working?
**Solution:** JavaScript execution is disabled for security. Only standard navigation links work.

### Can't edit content?
**Solution:** Double-click directly on the HTML content (not the node borders)

### Scrollbar appears unnecessarily?
**Solution:** The node has minimal padding; resize if you need more space

### Styling not applying?
**Solution:**
- Use inline styles with the `style` attribute
- Check for CSS syntax errors in your inline styles
- Predefined classes must be spelled exactly as documented

### Content not saving?
**Solution:** 
- Press **Escape** or click outside to exit edit mode
- Ensure you're not just closing the browser/tab
- Save your ComfyUI workflow after making changes
