Online sandbox workspace for HTML, CSS, JavaScript, and Python practice

This page is a dedicated coding workspace where you can edit HTML, CSS, JavaScript, and Python in one place. Frontend code runs with live preview, while Python runs in the built-in console, which makes the page useful for UI practice, scripting drills, and fast experiments without local setup overhead.

The workspace supports multiple layout modes, so you can place code, preview, and console in the format that matches your screen and workflow: top-bottom or side-by-side. This makes the page practical on laptops, wide monitors, and tablets where editor space directly affects productivity.

Use this sandbox for interview preparation, component prototyping, JavaScript behavior checks, and quick Python snippets with console output. Pro users can also ask AI to review selected code, suggest fixes, and speed up iteration while keeping full control over final output.

What this page gives you

  • Separate HTML, CSS, JavaScript, and Python editors in one focused workspace.
  • Instant preview for frontend code and console output for Python with optional auto-run.
  • Flexible code/preview layout modes for different screen sizes.
  • A practical training format for interviews and daily frontend practice.
