Reflow is one of the most practical accessibility requirements, ensuring content adapts without loss of information or function, even at 400% zoom or on small mobile screens. I break down how automated tools, AI-driven approaches, and manual testing each play a role in catching reflow issues, and why a blended approach is the most effective path to real accessibility.
Testing methods for WCAG 1.4.9 Images of Text (No Exception) ensures that text must be displayed using real text, not images of text, so it can be resized, styled, and read by assistive technologies.
WCAG 1.4.8 Visual Presentation ensures that users can control and adjust the visual presentation of text to improve readability and accessibility, especially for those with visual or cognitive disabilities.
WCAG 1.4.7 Low or No Background Audio requires speech to be easily heard without distracting background sounds, unless specific exceptions apply. Here’s how to test it using automated, AI-based, and manual methods.
WCAG 1.4.6 Contrast (Enhanced) ensures that text and images of text have an increased contrast ratio. Learn the pros and cons of the different testing methods; automated, AI-based and manual.
WCAG 1.4.5 Images of Text states that text should be displayed using actual text, not images of text, so it can be resized, styled, and interpreted by assistive technologies. This article highlights the pros and cons to using automated, AI-based and manual based testing.
Testing WCAG 1.4.4 Resize Text (Level AA) requires that users can enlarge text up to 200% without losing content or functionality. Automated tools flag code issues, AI highlights visual layout problems, and manual testing confirms usability, ensuring text remains readable, functional, and scroll-free at larger sizes.
Testing methods for WCAG 1.4.3 Contrast (Minimum), ensuring text and images of text maintain a contrast ratio of at least 4.5:1 against their background.
Testing WCAG 1.4.2 ensures users can pause, stop, or control the volume of any audio that plays automatically for over 3 seconds, without affecting system volume.
WCAG 1.4.1 Use of Color is a Level A conformance level Success Criterion. It requires that color alone must not be used to convey information.
Testing approaches for WCAG 1.3.6 Identify Purpose (Level AAA), which supports adaptable, personalized content for users with cognitive and learning disabilities.
WCAG 1.3.5 Identify Input Purpose ensures that each input field’s purpose can be programmatically determined if it matches a defined input purpose and is implemented using technologies that support semantic identification of form data.
WCAG 1.3.4 Orientation is a Level AA conformance level Success Criterion that ensures content should not limit viewing and interaction to only one screen orientation (portrait or landscape), unless a specific orientation is absolutely necessary.
WCAG 1.3.3 Sensory Characteristics is a Level A conformance level Success Criterion. It ensures that instructions for understanding and using content is not depend only on sensory attributes like shape, color, size, visual position, orientation, or sound.
WCAG 1.3.2 Meaningful Sequence ensures that the order of content on a webpage makes sense, even when someone isn’t looking at it visually.
WCAG 1.3.1 Info and Relationships states that information, structure, and relationships conveyed by the presentation must be discernible through text or programmatically.
WCAG 1.2.9 Audio-only (Live) is a Level AAA conformance level Success Criterion. It states that an alternative for time-based media that presents equivalent information for live audio-only content is provided.
WCAG 1.2.8 Media Alternative (Prerecorded) is a Level AAA conformance level Success Criterion. It states that an alternative for time-based media is provided for all prerecorded synchronized media and for all prerecorded video-only media.
WCAG 1.2.7 Extended Audio Description (Prerecorded) is a Level AAA success criterion, requiring videos to include extended spoken descriptions of visual content. When pauses in the main audio don’t fully convey the video’s meaning, extended audio descriptions are provided for all prerecorded, synchronized video content.
