OPEN THE HOOD ✳

The web comes with a lid you can open.

Start with the splash page’s real markup and styles, a small spring you can pull around, or a personal page to make your own. HTML gives it things, CSS gives them a look, and JavaScript gives them behavior.

Try CSS: find #b1f35d, choose another color, and run the preview.

Keep your version.

Save draft keeps it in this browser. Download HTML makes a standalone page you can open, edit, or host yourself. Images and other external files are not bundled.

Edits run inside the preview. The original site stays as it is. Links in the preview are paused so you can keep experimenting.

Built with locally hosted Ace. No account or build step. Keyboard trouble? Use a plain text editor.
