Overview

Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text.

Understanding

The W3C Web Accessibility Initiative (WAI) provides detailed guidance on understanding and implementing this criterion. The Understanding document covers the intent, benefits, and supporting techniques in depth.

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. Run an automated scan (e.g., axe-core) to detect structural markup issues.

  2. Verify headings (h1–h6) reflect document structure and are not used for visual styling only.

  3. Check that data tables use <th> for headers and have appropriate scope attributes.

  4. Confirm form fields have associated <label> elements or aria-labelledby.

  5. Review lists — ensure <ul>/<ol>/<dl> are used for actual list content.

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.
