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.
