Question 1 of 30
A government agency is undergoing a significant website overhaul to improve user experience and modernize its interface. Previously, the primary navigation menu was consistently located in the left-hand sidebar across all sections of the site. In the new design, the main navigation has been relocated to a hamburger menu icon in the top-right corner of every page, and the site search functionality, previously a prominent field in the header, is now also accessible only through this hamburger menu. This change was implemented without any prior user testing or advisory announcements regarding the shift in navigation patterns. What fundamental WCAG 2.1 principle is most directly compromised by this redesign, impacting users who rely on predictable interface elements?
