Axe violations axe-core 4.13.0, full rule set

27 violating nodes across 4 rules, 1493 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.

  • moderate region — All page content should be contained by landmarks 18 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 7 nodes
  • serious aria-input-field-name — ARIA input fields must have an accessible name 1 node
  • critical select-name — Select element must have an accessible name 1 node

Accessibility failures 5 of 31 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. 7 nodes
  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 5 nodes
  • aria-input-field-name — ARIA input fields do not have accessible names 1 node
  • aria-prohibited-attr — Elements use prohibited ARIA attributes 1 node
  • select-name — Select elements do not have associated label elements. 1 node
