## 🎨 Custom CSS Styling

The node uses an external CSS file (`AF-Enhanced-HTML-Note.css`) that you can customize to match your preferences or create your own styling themes.

### Editing the CSS

The CSS file is located at:
```
ComfyUI/custom_nodes/ComfyUI-AF-Enhanced-HTML-Note/web/AF-Enhanced-HTML-Note.css
```

You can edit this file directly to:
- Change colors of predefined sections (`.af-positive`, `.af-negative`, etc.)
- Modify spacing and padding
- Adjust font sizes and typography
- Create new custom section classes
- Change scrollbar styling
- Customize the edit button appearance
- OR **completely** replace the entire CSS and use your own classes. (Don't forget to change the classes in the HTML node in your ComfyUI workflow !!)

### Example: Creating a Custom Section Color

Add this to the CSS file to create a new teal section style:
```css
.af-html-note-content .af-section.af-teal {
    background: rgba(64, 224, 208, 0.1);
    border-left-color: #40E0D0;
}
```

Then use it in your HTML:
```html
<div class="af-section af-teal">
    <h3>🟢 Teal Section</h3>
    <p>Your custom styled content...</p>
</div>
```

**Note:** After editing the CSS file, refresh your browser (Ctrl+F5 or Cmd+Shift+R) to see the changes.

## 🐛 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
