Frequently Asked Questions

Find Quick Answers

Does this editor require an internet connection after loading?

No, once the page loads, all editing and preview functionality works entirely client-side in your browser without needing further internet connection.

Can I upload large HTML files?

Yes, you can upload HTML files of reasonable size (up to browser memory limits). The editor processes files locally without sending them to any server.

Does the editor support CSS and JavaScript?

The preview pane will render CSS and JavaScript included in your HTML code. However, the formatting toolbar only adds HTML tags - you need to write CSS and JavaScript manually in the editor.

Can I save my edited HTML?

Yes, use the 'Download HTML' button to save your current code as an .html file to your computer.
