Clusters krijgen een vingerafdruk via genormaliseerd selectorpad + regel-id + snippetvorm. Rangscore = (ernstgewicht × getroffen pagina's) / verschillende componenten voor de regel. Dit vervangt de template-drempelheuristiek, maar behoudt die als validatiesignaal.

Foutrapporten

4 probleemtype(n) worden standaard getoond van in totaal 21. Geprioriteerd op ernst, belangrijke pagina's, WCAG-niveau en prevalentie; gebruik de schakelaar om alles te tonen.

Algehele verdeling van ernst: 3 ernstig, 17 matig, 1 gering. Per WCAG-categorie: 6 WCAG 2.0 A, 1 WCAG 2.0 AA, 1 WCAG 2.1 A, 1 WCAG 2.2 AA, 3 WCAG 2.x AAA, 6 Beste praktijk, 3 Onbepaald. Geordend op ernst, impact op belangrijke pagina's, WCAG-niveau en prevalentie. Volgens de best practices voor het rapporteren van toegankelijkheidsbugs. Downloaden: Markdown · JSON (volledig archief) · JSON (AI-diagnose) · CSV (alle bevindingen) · CSV met prioriteitspagina's · JSON met prioriteitspagina's.

Automated testing does not establish full WCAG conformance. Findings in the verification lane require manual testing before they are treated as confirmed failures.

De standaardweergave toont 4 geprioriteerd(e) probleemtype(n); 17 meer zijn beschikbaar als u overschakelt naar "Alles tonen".

3 bevinding(en) gemarkeerd als "mogelijk duplicaat" — Alfa en axe-core markeerden beide hetzelfde WCAG-succescriterium op overlappende pagina's. Als ze hetzelfde element betreffen, is het axe-core-rapport doorslaggevend. Filter de CSV op possible_duplicate_of om deze te zien. Dat twee engines dezelfde barrière markeren, verkleint de kans op een vals positief.

Findings needing review

These findings need manual verification before they can be treated as confirmed failures. Obligation remains visible for each finding.

Impact

Affects Limited vision (2.4%), Without color perception (4.5%).

  • Limited vision — 2.4% van de bevolking
  • Without color perception — 4.5% van de bevolking

Getroffen pagina's

Testomgeving

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Voorgestelde oplossing

Hoe op te lossen: Increase the contrast between text and its background to at least 4.5:1 (3:1 for large text). Check both light and dark modes.

Drupal-tip: Check your Drupal theme's base CSS. Themes like Olivero and Bartik have contrast issues in default color schemes — override failing color pairs in your subtheme's style.css.

Testomgeving

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Voorgestelde oplossing

Hoe op te lossen: Use heading levels in order (h1 → h2 → h3) without skipping; structure, not size.

Drupal-tip: Drupal Views and blocks can insert headings at arbitrary levels. In the Views UI, set "Title tag" for each display. For block titles, configure the heading level in the block's layout settings.

Unieke toegankelijkheidsproblemen (axe + Alfa samengevoegd)

axe en Alfa implementeren beide de W3C ACT-regels, dus hetzelfde probleem wordt vaak door beide gevonden. Deze worden ontdubbeld per ACT-regel en pagina, dus een gedeelde bevinding telt één keer (2113 ruwe enginebevindingen → 2112 uniek).

Twee onafhankelijke implementaties van ACT-regels (Deque axe-core en Siteimprove Alfa) markeerden hetzelfde probleem op dezelfde pagina's. Overeenstemming tussen afzonderlijke engines is sterk bewijs dat de barrière echt is en geen vals positief van één tool — de beste plek om te beginnen.
