Landmark Structure

Action

No landmarks

FIX

No landmarks

No <main> landmark found

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

No <nav> landmark found

No banner (header) landmark

No contentinfo (footer) landmark

Skip navigation link is missing (WCAG 2.4.1)

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

No landmarks detected

Screen reader users have no way to navigate by region.

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

Why this matters

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Learn more ▾

The <main> element marks the page's primary content area. Assistive tech offers a 'jump to main' shortcut — but only if <main> exists. Without it, every page navigation forces re-reading the header. Wrap your primary content in a single <main>.

Source: WAI-ARIA / WCAG 2.4.1

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

Learn more ▾

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

Web Manifest

Action

Not found

FIX

Not found

No web manifest found

No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

No web manifest found.

Dark Mode Support

Action

No dark mode signals

FIX

No dark mode signals

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

No print styles

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

85 links, 0 buttons — all OK

REVIEW

85 links, 0 buttons — all OK

5 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="/notificaciones/"]; a[href="/edictos_judiciales/"]; a[href="https://subastas.boe.es/"]; a[href="/anuncios"]; a[href="/datosabiertos/api/api.php"]

3 link(s) open in new tab without warning

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

a[href="/notificaciones/"]; a[href="/edictos_judiciales/"]; a[href="https://subastas.boe.es/"]; a[href="/anuncios"]; a[href="/datosabiertos/api/api.php"]

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.

http://eur-lex.europa.eu/JOIndex.do?ihmlang=es; http://hj.tribunalconstitucional.es/; https://www.poderjudicial.es/search/indexAN.jsp

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.

Lighthouse Accessibility Audits

Score 92/100 — 2 failing, 18 passed

PASS

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.

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.

Why this matters

Performance issues directly impact user engagement and conversion rates.
