Hamburger Menu

Sticky Navigation Cannot reliably detect (CSS-based)

1 of 6 testable patterns navigation patterns detected. Limited navigation support. Consider adding breadcrumbs, search, and skip link.

Landmark Structure

15 landmarks

REVIEW

15 landmarks

<main> landmark present

No <nav> landmark found

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.

Page Structure — as a screen reader sees it

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.

Form Accessibility

2 of 2 controls have issues

REVIEW

2 of 2 controls have issues

2 control(s) rely on placeholder only

Placeholder text disappears on focus and is not a reliable label.

Got: <input type="text" id="search-with-autocomplete">; <input type="text" id="search-global-input">

2 controls

0 labeled

2 placeholder only

0 unlabeled

Control	Type	Label	Method
#search-with-autocomplete	text	(Cosa stai cercando?)	placeholder only
#search-global-input	text	(Cosa stai cercando?)	placeholder only

Placeholder text disappears on focus and is not a reliable label.

Why this matters

Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Learn more ▾

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).

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

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.

Heading Hierarchy

11 headings, 1 skip(s)

PASS

11 headings, 1 skip(s)

Single H1 present

Heading level skipped: H1 → H3 (missing H2)

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

H1 VQR: i numeri da record della ricerca Unipd
H3 Campus multisede skipped
H3 Aule e spazi per lo studio
H3 Residenze e alloggi
H3 Benessere e sport
H3 Scoprire la città
H2 Raccontiamo il mondo che cambia ne Il Bo Live
H3 La convergenza tecnologica nelle osservazioni della Terra dallo spazio
H3 Concetto Marchesi dalla Resistenza alla Costituzione
H3 Anatomia del corpo umano, dalle immagini su carta al 3D
H3 Senza perdere tempo. La rigenerazione naturale di una foresta pluviale tropicale

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

Why this matters

Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.

Learn more ▾

Screen reader users navigate by jumping between headings (H1 → H2 → H3). Skipping (H1 → H3) breaks the sense of hierarchy. Use sequential levels even if you don't like the default styling — restyle with CSS instead. WCAG 1.3.1 (Info and Relationships) treats this as an A failure.

Lighthouse Accessibility Audits

Score 99/100 — 1 failing, 29 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.

Navigation

Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more about heading order.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Campus multisede `div.MuiStack-root > div.MuiBox-root > div.MuiPaper-root > h3.MuiAccordion-heading`
