This URL redirects to https://dsev.dk/.

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.

resource load delay 137 ms
element render delay 115 ms

Axe violations axe-core 4.13.0, full rule set

9 violating nodes across 4 rules, 389 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 4 nodes
  • serious aria-hidden-focus — ARIA hidden element must not be focusable or contain focusable elements 3 nodes
  • critical button-name — Buttons must have discernible text 1 node
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 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. 4 nodes
  • aria-hidden-focus — `[aria-hidden="true"]` elements contain focusable descendents 3 nodes
  • button-name — Buttons do not have an accessible name 1 node
