video-caption

Verify that <video> elements include captions for comprehensive accessibility.

Severity: Critical

Description

Incorporate a track element with kind="captions" in HTML5 videos to provide essential details like dialogue, music, and sound effects for users with hearing impairments.

Why is it important?

Lack of video captions limits access for deaf users. Ensure captions encompass all essential information, not just dialogue, enabling meaningful comprehension without sound.

How to fix?

Include a caption for video elements by utilizing the track element with the caption property. Ensure the caption encompasses all pertinent details within the video, like dialogue, musical cues, and sound effects, among other elements.
