Web Accessibility Tip: Consistent Navigation and Identification

Consistency is important for web site accessibility and usability. WCAG 2.0 Success Criterion 3.2.3 (Level AA) requires that navigation elements that are repeated on web pages do not change order across pages. Success Criterion 3.2.4 (Level AA) requires that elements that have the same functionality across multiple web pages be consistently identified. For example, a search box at the top of the site should always appear in the same place and be labeled the same way.
