Frequently Asked Questions

Finn raske svar

Does this tool require an internet connection after loading?

Once the page loads, all processing happens locally in your browser. You can use the tool offline after the initial load.

Can I save my work?

Yes, you can download your complete project (HTML, CSS, and JavaScript files) as a ZIP file using the Download button.

Is there a file size limit?

Since all processing happens in your browser, the only limit is your device's memory. However, for optimal performance, we recommend keeping individual code panels under 10,000 lines.

Does this tool support frameworks like React or Vue?

The tool provides a basic HTML/CSS/JavaScript environment. You can include framework libraries via CDN links in your HTML, but there's no built-in framework-specific tooling.
