Three Flashes
Success Criterion 2.3.2 (Level AAA)


Have you ensured that your website/application does not contain content that flashes?

Why is this important

Content that flashes can trigger seizures in users who suffer from photosensitive epileptic seizures, be an additional distraction for learners with cognitive/learning disabilities, as well as distract and frustrate some users in general.

Whom does it benefit?

Example 1:

As a person with epilepsy,
I want web content presented without flashing or fast blinking,
so that I can access the information without the potential of triggering a seizure.

Example 2:

As a student with an attention deficit disorder,
I want information presented without unnecessary distractions,
so that I can concentrate and focus on the assignment at hand.

What should you do?

Do not design content that flashes.

While WCAG allows for content that flashes under certain, very strict parameters, it is strongly suggested to refrain from using flashing content at all. Furthermore, in the type of educational content that Pearson produces, there is no need to use flashing or blinking content. Therefore, adding any sort of flashing content could be hazardous and of very little gain for the end users.

How do you do it?

Flashing content should not be used anywhere. If already in existence, remove the flashing content and replace with non-flashing content that conveys similar meaning or information.
