What the checks mean
| Check | Error when | Reference |
|---|---|---|
| Page overflow | The page is wider than the viewport, so it scrolls sideways. Names the elements that make it wide. | — |
| Cut-off control | A button, link or field is cut off by a container that clips and does not scroll. A control inside a scrollable box is fine. | — |
| Sticky that cannot stick | position: sticky inside a box that never scrolls on that axis. An error when its offset also pushes it over the content; a warning otherwise. |
CSS Positioned Layout |
| Small touch target (warning) | Smaller than 24×24px and too close to another target. A small target with enough space around it passes, as the rule allows. | WCAG 2.2 SC 2.5.8 |
Contrast (--inspect) |
Under 4.5:1, or 3:1 for large text. Measured against a gradient's worst stop. | WCAG 2.2 SC 1.4.3 |
