Starter examples

Helpful tips

- Use the starter cards when you want a quick example instead of a blank editor.
- Click Run preview after edits so the preview stays stable while you type.
- Add CSS inside style tags and JavaScript inside script tags for full-page examples.
- If you came from a lesson, Reset returns to that lesson code instead of the default starter.
