Techniques

W3C provides documented techniques for meeting this criterion. Each technique links to the full specification with code examples and test procedures.

How to Test

  1. Identify the specific content or feature this criterion applies to on the page.

  2. Verify the content is accessible to users who cannot perceive it in its default modality.

  3. Test with assistive technology (screen reader, screen magnifier) to confirm accessibility.

  4. Check that no information is conveyed solely through visual means.

How VPATify tests this

VPATify runs automated WCAG checks against every page you scan and flags violations against individual success criteria. Our deep scan combines axe-core, contrast analysis, and structural checks to catch criterion-level failures that single-tool scans miss. See the full testing methodology and features for what's covered at each level.
