Semantic Accessibility

An approach to web accessibility that focuses on the predictability and consistency of user interface behavior, layout, and interaction patterns rather than the underlying code. Semantic accessibility ensures that similar elements appear in the same locations across pages, menus are organized consistently, and interactive components behave in predictable ways. While syntactic accessibility addresses whether assistive technologies can technically parse content, semantic accessibility addresses whether all users — including older adults and people with cognitive disabilities — can understand and anticipate how a system works based on its structure and patterns.
