Write HTML markup to structure your page. Your code runs in a sandboxed preview showing the rendered output.

Write CSS to style elements. The preview displays a showcase of buttons, cards, and typography to see your styles live.

Write JavaScript to add logic. The preview shows a real-time console with console.log, errors, and execution output.

Each language saves automatically as you type, so your code is still there next time you visit CodePad.

Tap the "Run Code ⚡" button in the editor header to execute your code and jump to the preview. Use Refresh to re-run without losing your editor content.
