Embedded Animation That Blinks for Over 5 Seconds Nonstop
2.2.2 — Pause, Stop, Hide
Scenario
Setting
A university's online course catalog
What’s wrong
An embedded object or animation blinks for more than 5 seconds and there is no way to pause or stop it.
Example
During an audit of a university's online course catalog: an embedded object or animation blinks for more than 5 seconds and there is no way to pause or stop it.
Why it matters
People with attention disabilities, low vision, or screen-reader users who lose place when content moves. On a university's online course catalog specifically, they can't keep up with content that won't pause.
How to test
Time any blinking object/embedded content: beyond 5 seconds with no pause mechanism, it fails.
How to fix
Stop the blinking within 5 seconds or provide a pause/stop control for the embedded content.
Outcome
Fixed, a visitor to a university's online course catalog can read the content without losing their place.
Who is affected
People with attention disabilities, low vision, or screen-reader users who lose place when content moves.
