Frequently Asked Questions
Can I save my HTML from the editor?
Yes — use the download button inside the editor to save your HTML file locally. You can also select all (Ctrl+A), copy (Ctrl+C), and paste into your own code editor or file.
Does it support CSS and JavaScript?
Yes — you can write full HTML pages including embedded CSS in <style> tags and JavaScript in <script> tags. The live preview renders the full page including your styles and scripts.
Is my code saved between sessions?
Code is stored in your browser's local storage while the editor is open. If you close the browser or tab, your work may not be preserved. Always save your work using the download button before closing.
Can I use it to test email templates?
Yes — paste your HTML email code into the editor and preview it. Keep in mind that email clients support a limited subset of CSS, so the preview (which uses a full browser) may look different from how the email renders in Gmail or Outlook.
