Health index
Implementation
Most accessibility concerns should be covered by implementing health index per our guidelines. You can double-check your implementation by ensuring the following:
- Health index should not be interactive or keyboard-focusable
- Health index should be placed in a context that makes its purpose clear to all users—with and without assistive technologies
- Health index should communicate its grade both visually and to assistive tech
Test your experience with a keyboard and screen reader to help verify
these accessibility conformance checks. <rh-health-index> should present to
assistive technology using the meter role and corresponding ARIA
attributes to communicate to assistive technology. Inspect this element using
the DevTools Accessibility Tree to see each value.
