Dark Mode Support

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: #4f0433

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.

Alt Text Quality

3 of 23 images have issues

REVIEW

3 of 23 images have issues

3 image(s) missing alt attribute

Images without alt text are invisible to screen readers.

20 image(s) with good alt text

23 images 20 good alt text 3 missing

Issue	Count
missing	3 image(s)

Images without alt text are invisible to screen readers.

Why this matters

Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.

WCAG 2.1 Level A requires text alternatives for non-decorative images. Empty alt='' is fine for decorative; meaningful images need descriptive text. Common fixes: CMS audit + bulk add, build-time linter (alt-text-required ESLint rule), CI gate on Lighthouse a11y score.

a#main-content

Why this matters

Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.

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.

Icon-only buttons need an aria-label so screen readers can announce them.

button (#87 on page); button (#90 on page); button (#93 on page); button (#96 on page); button (#101 on page); button (#104 on page)

Why this matters

Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.

Lighthouse Accessibility Audits

Score 84/100 — 4 failing, 29 passed

REVIEW

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

ARIA

Each ARIA `role` supports a specific subset of `aria-*` attributes. Mismatching these invalidates the `aria-*` attributes. Learn how to match ARIA attributes to their roles.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Meny `div > div.container > div.utilities > div#main-menu_toggle`

Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid values. Learn more about valid values for ARIA attributes.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Anpassa dina kakor `div.wrapper > div.footer__col > p > a.js-cookie-settings-link`

These are opportunities to improve the usage of ARIA in your application which may enhance the experience for users of assistive technology, like a screen reader.

Names and labels

Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the `alt` attribute.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
div > div.hero-frontpage > picture > img `div > div.hero-frontpage > picture > img`

These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.

Best practices

Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.
