Silent Background Video That Actually Shows Product Info
1.1.1 — Non-text Content
Scenario
Setting
An online spreadsheet's toolbar
What’s wrong
Background video (video-only, decorative) that actually conveys information (e.g., product demo) with no text alternative.
Example
Try this on an online spreadsheet's toolbar: background video (video-only, decorative) that actually conveys information (e.g., product demo) with no text alternative.
Why it matters
Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning. The practical effect on an online spreadsheet's toolbar: they get no equivalent for the sound or picture content.
How to test
Watch the background video with sound off: if the video conveys information relevant to the page (a product demo, a diagram in motion) with no caption or transcript, it fails.
How to fix
Provide a text alternative describing what the informative background video shows.
Outcome
That one change on an online spreadsheet's toolbar means they get the same information as everyone else.
Who is affected
Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning.
