Accessibility testing status

For every latest release, Carbon runs tests on all components to meet the accessibility requirements. These different statuses report the work that Carbon has done in the back end. These tests appear only when the components are stable.

Latest version: ^1.48.1 | Framework React (@carbon/react)

How it works

Tags are used for web content that needs to be labeled, categorized, or organized using keywords that describe them. Tags are often used as a filter where all tags are in the same color, or used when content is mapped to multiple categories, where color is used to differentiate between categories.

Accessibility considerations

This component has been validated to meet the WCAG 2.0 AA and Section 508 accessibility guidelines, however changes made by the content owner can affect accessibility compliance. Be sure to review and follow the guidance in this section when updating or adding new content to this component.

  1. Be sure the tag text is clear and concise.
  2. Color should not be used as the only means to differentiate tag categories.
  3. When using custom colors be sure the minimum contrast requirements are met.
  4. Tags that are modified as a link to filter content should also follow the link Carbon Component guidance.
