This URL redirects to https://craigerskine.github.io/11ty-twind/.

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

2 violating nodes across 2 rules, 456 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 landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
  • serious scrollable-region-focusable — Scrollable region must have keyboard access 1 node
