This URL redirects to https://sevenpx.design/drawings/.

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.

Filmstrip Lighthouse, mobile

How the page drew during the measured load, at 8 points across 3.00 s.

Without JavaScript

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

24% of pixels differ — parts of the page change. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.

What LCP is made of observed, unthrottled

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

Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 4.09 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

Axe violations axe-core 4.13.0, full rule set

0 violating nodes across 0 rules, 479 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.
