Try it

Documentation demo

Use the Live demo, React, AI prompt, and Packaging / Manifest tabs below. Embedded demos disable telemetry, xAPI, and the LMS bridge. For production delivery, use the CLI template src/courseConfig.ts and LMS Go-Live.

Open demo in full tab 

<ImageJuxtaposition
  blockId="workspace-jux"
  beforeSrc="/desk-cluttered.jpg"
  afterSrc="/desk-clean.jpg"
  beforeAlt="Cluttered desk with visible notes"
  afterAlt="Clean desk with locked screen"
/>

Copy into Cursor, Copilot, or ChatGPT after the vibe coding starter context:

Read lessonkit.json and src/App.tsx before editing.

Add a ImageJuxtaposition block (H5P-style: Image Juxtaposition) like this example inside the active <Lesson>:

<ImageJuxtaposition
  blockId="workspace-jux"
  beforeSrc="/desk-cluttered.jpg"
  afterSrc="/desk-clean.jpg"
  beforeAlt="Cluttered desk with visible notes"
  afterAlt="Clean desk with locked screen"
/>

Requirements:
- Import only from @lessonkit/react; use block types from block-catalog.v3.json.
- Keep existing courseId, lessonId, and navigation stable unless I ask to add a lesson.
- After edits, list changed files and what to verify in the browser (lessonkit dev).
