Frequently Asked Questions (FAQs)

Can I use external libraries like Bootstrap or jQuery?

Yes! You can easily include external CDNs by adding the standard <link> or <script> tags directly inside the HTML editor, just as you would in a normal web project.

Why isn't my JavaScript running?

Ensure that your code doesn't contain infinite loops, as this will crash the preview frame. Also, check for syntax errors. You can use your browser's Developer Tools (F12) to inspect the iframe console for errors.
