The tooltip React Carbon component has been tested against the latest W3C Web Content Accessibility Guidelines (WCAG) 2.1 Level A and AA success criteria and violations have been identified as high priority issues. This document will be updated when these accessibility issues are resolved.
- After the tooltip opens, initial focus should be set on the first focusable element in the tooltip. See WAI-ARIA Authoring Practices Modal Dialog Example, Accessibility Features section for best practices on setting focus. Note: This does not apply to the tooltip icon or tooltip definition components.
- After the tooltip closes, focus should retain the user’s point of regard and return to the element that invoked it. Note: This does not apply to the tooltip icon or tooltip definition components where focus never leaves the element that invokes it.
- The tooltip component’s focus must not move outside the modal until it is closed. Note: This does not apply to the tooltip icon or tooltip definition components, as noted above, focus never leaves the element that invokes it.
- The tooltip component has the same accessibility considerations as outlined in the modal component documentation.
- W3C WAI-ARIA Authoring Practices Tooltip Design Pattern covers the usage of ARIA names, state and roles, as well as the expected keyboard interactions.
