Shareable Code Runner

This is a small static site that lets you edit and run HTML, CSS, JavaScript, and simple Python (via Pyodide) in the browser. Perfect for sharing quick examples with friends.

Files

• index.html — main editor and preview UI
• style.css — styling
• runner.js — client-side runner and share helpers

Run locally

1. Start a simple HTTP server from the repository root (recommended):

python3 -m http.server 8000

2. Open http://localhost:8000 in your browser.

Notes

• Use the mode selector to pick HTML/CSS/JS/Python.
• For Python, the first run will download Pyodide (WebAssembly) from a CDN — it may take a few seconds.
• Click "Share" to copy a link with the code encoded in the URL hash. Paste and share that URL with friends.

Deploy to GitHub Pages

1. Commit and push the repo to GitHub.
2. In the repository settings, enable GitHub Pages from the main branch (root). The site will be served at https://<your-user>.github.io/<repo>/.

Security

This project runs arbitrary JavaScript in an iframe; do not load untrusted external scripts. The Python support runs in Pyodide inside the browser sandbox.
