Accessibility failures 6 of 33 audits

Tracked as a count, not just the score — the weighted score is coarse enough that you can ship a broken component and barely move it.

  • link-name — Links do not have a discernible name 6 nodes
  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 3 nodes
  • aria-hidden-focus — `[aria-hidden="true"]` elements contain focusable descendents 2 nodes
  • button-name — Buttons do not have an accessible name 1 node
  • link-in-text-block — Links rely on color to be distinguishable. 1 node
