Node Management

🎨 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:

.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:

<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>Common Issues and Solutions</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
