WCAG 1.1.1: Non-text Content
Published by whatisADA / Grow Wild Agency · Updated
What this criterion means
Make the purpose or information in non-text content available through text. The right alternative depends on how the image is used: a product photograph, a linked icon and a decorative divider need different treatment.
A practical example
A store shows a backpack from three angles. Describe the useful visual differences in each image. If a small cart icon sits inside a button already labeled “View cart,” hide the redundant icon from assistive technology.
How to check it
- List images, SVGs, icon buttons, charts and canvas content in the chosen page state.
- Decide which information or action each conveys in this context, then inspect its accessible name or adjacent alternative.
- Read the alternatives without seeing the images and complete the same task, including any chart interpretation.
What can be missed
An alt attribute existing is not proof that its wording is useful. Complex diagrams may need a short name plus a nearby detailed explanation; decorative images usually need an empty alternative.

These are your observations, not automated results or a conformance certificate. A complete evaluation needs appropriate scope, supported technologies, all applicable criteria and relevant page states.
Primary sources and scope
This is independent implementation guidance with original examples. The linked standard contains the full definitions, exceptions and conformance requirements. A criterion or checklist alone does not establish legal applicability or whole-site conformance.
