WCAG 2.3.2: Three Flashes


This post, as with our last article on WCAG 2.3.1, deals with flashing content and the danger it poses to those prone to seizures. Whereas WCAG 2.3.1 describes the Level A standard for flashing content, this rule describes the AAA level. In other words, if you want your site to meet this guideline, it’ll be a higher bar to clear.

The chance for seizure, unfortunately, can never be completely eliminated, since some people are hypersensitive to this condition. This guideline seeks to further reduce that risk, however, by asking that your site not contain any content that flashes at a rate of at least three times per second, regardless of the color, size, or dimness of the flashes.

As we discussed in our last post on WCAG 2.3.1, there are a number of tools you can download that will help you analyze your site and determine whether there is any content that would pose a risk to those prone to seizures. We recommend using this free tool designed by the University of Maryland’s Trace Research and Development Center. This will be the surest way to ensure your site is safe for everyone to use.
