- Success Criterion 2.3.1
- Conformance level A
Rapid Full-Screen Color Flash on Load or Error
2.3.1 — Three Flashes or Below Threshold
Scenario
Setting
A real-estate marketplace's listing page
What’s wrong
Rapid full-screen color inversion animations on load or error states.
Example
During an audit of a real-estate marketplace's listing page: rapid full-screen color inversion animations on load or error states.
Why it matters
People with photosensitive epilepsy and others sensitive to rapid flashing. On a real-estate marketplace's listing page, that means they can't keep up with content that won't pause.
How to test
Review any rapid full-screen color-inversion animation (on load or error states) with PEAT: above-threshold flashing fails.
How to fix
Nothing may flash more than 3 times per second above the general or red-flash thresholds.
Outcome
With the fix in place on a real-estate marketplace's listing page, they finish the task at their own pace.
Who is affected
People with photosensitive epilepsy and others sensitive to rapid flashing.
