404 Error Page

FIX

HTTP 404, bare page

Correct 404 status code returned

Got: HTTP 404

Bare server default 404 page

The 404 page has no custom styling. Users hitting a broken link see a generic error with no way to navigate back. Add a custom 404 page with your site navigation and a search bar.

Dark Mode Support

Action

Theme color only

FIX

Theme color only

Theme-color present but no dark variant

A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.

Got: #ffffff

No dark mode signals detected

Consider adding CSS with @media (prefers-color-scheme: dark) and <meta name='color-scheme' content='light dark'>.

Detection limited to meta tags and inline styles

External CSS files may contain prefers-color-scheme rules not visible to this scan.

Print Stylesheet

Action

FIX

No print styles

No print-specific styles detected

When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

Link & Button Quality

16 links, 1 buttons — all OK

REVIEW

16 links, 1 buttons — all OK

1 image-only link(s) without alt text

Image-only links need alt text on the image (or aria-label on the link) so screen readers can announce them.

Got: a[href="/"]

3 link(s) open in new tab without warning

Add '(opens in new tab)' to link text or aria-label.

13 links and buttons have descriptive text

Image-only links need alt text on the image (or aria-label on the link) so screen readers can announce them.

a[href="/"]

Why this matters

Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.

Source: WCAG 2.1 SC 2.4.4

Add '(opens in new tab)' to link text or aria-label.

Why this matters

Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.

Learn more ▾

Without rel="noopener", the new tab can navigate the original tab via window.opener (tab-nabbing attack). Modern browsers default to noopener for target=_blank but only since recent versions. Always set rel="noopener noreferrer" explicitly.
