Frequently Asked Questions (FAQ)

Q: What code is supported?

A: The previewer supports standard HTML markup, CSS styling blocks (within <style> tags), and client-side JavaScript (within <script> tags).

Q: Can I use CSS framework libraries?

A: Yes. You can load external stylesheet libraries by using HTML link tags (e.g. linking to Bootstrap or Tailwind CDN distributions).

Q: Are my codes uploaded to a server?

A: No. All code compilation runs locally in browser memory, ensuring privacy.

Q: Why does JavaScript alert fail inside the preview?

A: The sandboxed preview environment blocks popups and modals like alert() to protect the browser window, but console logs function normally.
