Metrics LAB

No field data: the Chrome UX Report is not being collected for this project, so every figure below is from the Lighthouse run.

LCP Subparts LAB Unthrottled

The subparts attribute LCP to your server, resource discovery, download, or rendering. Note that the Lab LCP shown above is a simulated throttled estimate.

Axe violations axe-core 4.13.0, full rule set

31 violating nodes across 3 rules, 440 passing. This is a standalone Axe CLI run and is stricter than the subset Lighthouse already includes.

  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 28 nodes
  • serious link-name — Links must have discernible text 2 nodes
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node

Accessibility failures 2 of 27 audits

  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 28 nodes
  • link-name — Links do not have a discernible name 2 nodes
