Axe violations axe-core 4.13.0, full rule set

19 violating nodes across 5 rules, 812 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.

  • serious link-name — Links must have discernible text 7 nodes
  • moderate region — All page content should be contained by landmarks 6 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 4 nodes
  • moderate heading-order — Heading levels should only increase by one 1 node
  • moderate landmark-one-main — Document should have one main landmark 1 node

Accessibility failures 4 of 14 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 7 nodes
  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 4 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
