This URL redirects to https://disjfa.github.io/eleventy-encore/.

A trailing slash only, so both forms are treated as one site rather than two — one history, measured once. Lighthouse follows the redirect, so the numbers below describe the canonical page; the only cost is an extra hop on each run.

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

23 violating nodes across 4 rules, 141 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 color-contrast — Elements must meet minimum color contrast ratio thresholds 18 nodes
  • moderate heading-order — Heading levels should only increase by one 2 nodes
  • moderate region — All page content should be contained by landmarks 2 nodes
  • moderate landmark-one-main — Document should have one main landmark 1 node

Accessibility failures 3 of 22 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. 18 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 2 nodes
  • landmark-one-main — Document does not have a main landmark. 1 node
