This URL redirects to https://incubator.apache.org/projects/annotator.html.

Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. Not yet confirmed as a move; it needs to lead to the same place on several consecutive runs first.

Stack

Detected on the same page load as the accessibility pass — the generator from <meta name="generator"> or the shape of the page, the host from response headers.

What LCP is made of

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Axe violations axe-core 4.13.0, full rule set

31 violating nodes across 8 rules, 699 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 17 nodes
  • critical image-alt — Images must have alternative text 7 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 2 nodes
  • serious html-has-lang — <html> element must have a lang attribute 1 node
  • critical label — Form elements must have labels 1 node
  • moderate landmark-one-main — Document should have one main landmark 1 node
  • serious link-name — Links must have discernible text 1 node
  • moderate page-has-heading-one — Page should contain a level-one heading 1 node

Accessibility failures 7 of 17 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.

  • target-size — Touch targets do not have sufficient size or spacing. 31 nodes
  • image-alt — Image elements do not have `[alt]` attributes 7 nodes
  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 2 nodes
  • html-has-lang — `<html>` element does not have a `[lang]` attribute 1 node
  • label — Form elements do not have associated labels 1 node
  • link-name — Links do not have a discernible name 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
