When a document contains an element that is not native text, it needs to contain a description so non-visual users can understand what is being conveyed. The text description should explain what the element is conveying, not necessarily what it looks like. Some examples on non-text content would be:
- Word Art
- Decorative images such as backgrounds
All non-text items that have meaning (background or aesthetic images are excluded) must include descriptive text equivalents that convey the same meaning as the visual item.
Benefits to Users and Developers
- Text equivalents appears as a Tool Tip providing additional information for all users.
- Text equivalents establish context, provide visual interest, or assist with navigation.
- Text equivalents provide visual information in a non-graphical environment.
- Users of assistive devices such as screen readers or refreshable Braille use text equivalents to describe non-text items.
