Have you ever seen this warning?
Did you take it seriously?
It can be easy to overlook a warning that does not impact you.
Now imagine you suffer from seizures and you want to do some research for a paper. Websites don’t usually have these warnings, so you run the risk of stumbling upon a site that could cause you to have an attack. It’s a scary thought.
Business Owners and web designers don’t mean to overlook this, and yet a beautifully designed site can cause a lot of harm without meaning to. But breathe easy; this is the reason the 508 guidelines were developed.
Section 508 of the Rehabilitation Act of 1973 ensures that websites are accessible to everyone; the visually impaired, the autistic community, people with anxiety disorders, epilepsy, etc. As business owners we want our website to be consumable by everyone. We don’t want to alienate an entire group.
The compliance guideline that addresses the concerns of people suffering from seizures is:
(j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz.
Following this guideline gives us the peace of mind that our sites will not cause anyone harm, our content is available to this demographic, and there will be no adverse consequences for us or our viewers.
