How to Test Front-End Code Safely
Add the page structure to the HTML editor, place visual rules in the CSS editor, then use the JavaScript panel for interactions. The preview updates as you type, so you can check a small component before adding it to a larger project. Export the result when you need a single HTML file, or copy each panel separately for an existing codebase.
The preview runs in an isolated frame. It is suitable for layout experiments, examples and small interface tests, but it does not replace browser testing on the final website. Check keyboard behaviour, responsive layouts and error handling in the real project before publishing. Do not paste passwords, API keys, customer data or other confidential information into browser-based coding tools.
