Multimedia Accessibility
Checks for the presence of captions or transcripts for <video> and <audio> elements.
What is this check?
This check looks for `<video>` or `<audio>` elements and verifies if they have associated captions or transcripts.
Why is it important?
Users who are deaf or hard of hearing require captions to understand the audio content of a video. Audio content should have a text transcript available.
What is the impact?
Without captions or transcripts, multimedia content is completely inaccessible to users with hearing impairments.
Example Implementation
<video controls>
<source src="movie.mp4" type="video/mp4">
<track src="captions_en.vtt" kind="captions" srclang="en" label="English">
</video>
