W3 Accessibility Guidelines General Information

Non-Visual Text

All non-text content that is presented to the user has a text alternative that serves the equivalent purpose

The intent of this Success Criterion is to make information conveyed by non-text content accessible through the use of a text alternative. Text alternatives are a primary way for making information accessible because they can be rendered through any sensory modality (for example, visual, auditory or tactile) to match the needs of the user.
