Visual Content Accessible Alternative Check
Description
The “Visual Content Accessible Alternative Check” evaluates whether <video></mark> elements that present visual-only or visually significant content (like action, facial expressions, or charts) include an accessible alternative.
Example outcome
I noticed that there is 1 <video></mark> element with visual content that must have an accessible alternative.
Impact
- Visual Impairments: Visually impaired individuals may miss key visual content such as actions, gestures, charts, etc.
- Cognitive Disabilities: Users with cognitive disabilities may rely on clear audio description to process visual sequences.
Fixes
To address missing visual content accessible alternatives:
- Locate the inappropriate
<video></mark> element. - Provide either an audio description or a text transcript.
