## AI overview

The article explains how dynamic website behavior, including unexpected notifications, automatic refreshes, and other interruptions, can create accessibility barriers for screen reader users and people with attention disorders. It discusses WCAG Success Criterion 2.2.4, which says interruptions can be postponed or suppressed except in emergencies, while noting that this Level AAA criterion is not generally required for conformance goals.
