Accessibility failures 3 of 26 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.

  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 15 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 1 node
  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 1 node
