WCAG 1.4.8 Visual Presentation is a Level AAA success criterion that ensures users can customize text appearance for better readability. It requires user-selectable colors, text blocks under 80 characters wide, no justified text, proper line spacing, and 200% text resizing capability. The criterion primarily benefits people with cognitive disabilities. Testing approaches include automated tools for detecting justified text and character limits, AI for analyzing visual patterns, and manual testing for real-world usability. A combined approach using all three methods provides the most comprehensive assessment of compliance and usability.
