Glossary · Indexing and discovery

accessibility structure

What can be read about accessibility from the document a server returns, without rendering it: a lang attribute, a title, alt on images, names on form controls and buttons, titles on frames, a main landmark, a skip link or landmarks, unique ids. A screen reader depends on all of these before contrast or focus order ever matters. Measured here; a WCAG audit is not.

Terms this definition uses
