Frequently Asked Questions
Is the live preview executed securely?
Yes. The preview executes inside a sandboxed iframe with strict security policies to isolate the running script from your primary browser session.
Can I include external CSS libraries like Tailwind or Bootstrap?
Yes! Simply add a `<link rel="stylesheet" href="...">` tag to the `<head>` of your HTML code to import any external CDN stylesheet.
Does this editor save my code if I refresh?
Your current code is automatically cached in your browser's local storage so you never lose work on accidental page reload.
