Tabs
The tabs 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.
Accessibility considerations
- Each tab must have a unique title that clearly describes tab panel content. This is particularly helpful for users of assistive technologies so they have the necessary information to efficiently navigate the content.
- Carbon components should be used to create the content that displays within each tab panel.
- Content authors need to ensure the content that is added to the tab panel is accessible. For example, if you add an image to the panel you need to include alternative text to pass accessibility testing.
Resources
- W3C WAI-ARIA Tab Design Pattern covers the usage of ARIA names, state and roles, as well as the expected keyboard intractions.
