Lesson 5 of 5 · Video
Make videos playable and understandable
What it is
Use modern embeds (YouTube or HTML5 video) with play controls. Add captions and a transcript or summary on the page.
Why it matters
Captions help viewers with sound off and deaf visitors; transcripts give search engines text to understand.
✓ Good example
A 'how we install' video with captions and a written summary below.
✗ Common mistake
An autoplaying video with no controls and no text.
You pass when: Videos have controls, captions and on-page text.
