www.cms.gov: Toegankelijkheid — week 2026-W40

Automated Accessibility Conformance Report (OpenACR): Download ACR. Machine-readable; compatible with GSA OpenACR tooling. Automated tools find ~⅓ of real barriers — supplement with manual AT testing.

Training priorities

Top WCAG success criteria by pages affected this week. Use these to focus team training on the highest-impact issues.

SC	Criterion	Pages	Rules	Notes
1.4.8	WCAG 1.4.8	216	4
2.5.5	WCAG 2.5.5	155	1
1.4.1	Use of Color	142	2
1.3.1	Info and Relationships (semantic structure)	133	5	Component inconsistency
3.1.1	Language of Page	115	2

Volgende 10 acties

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.

Afstemming op design system (cms-ds / default). Geen design-systemcomponenten gedetecteerd in de gesamplede bevindingen.

Foutrapporten

7 probleemtype(n) worden standaard getoond van in totaal 31. Geprioriteerd op ernst, belangrijke pagina's, WCAG-niveau en prevalentie; gebruik de schakelaar om alles te tonen.

Algehele verdeling van ernst: 2 kritiek, 5 ernstig, 22 matig, 2 gering. Per WCAG-categorie: 10 WCAG 2.0 A, 2 WCAG 2.0 AA, 1 WCAG 2.2 AA, 2 WCAG 2.x AAA, 9 Beste praktijk, 7 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 7 geprioriteerd(e) probleemtype(n); 24 meer zijn beschikbaar als u overschakelt naar "Alles tonen".

2 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.

Stappen om te reproduceren

…en meer — alle 106 pagina's (CSV).

Testomgeving

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

Voorgestelde oplossing

Hoe op te lossen: Add a lang attribute to <html> (e.g. lang="en").

Drupal-tip: Drupal sets the page lang attribute from Admin › Configuration › Regional and Language › Languages. Ensure the default language is configured.

Voorgestelde oplossing

Hoe op te lossen: Give every <img> a meaningful alt attribute. Use alt="" only for decorative images so screen readers skip them.

Drupal-tip: In Drupal's Media Library, fill the "Alternative text" field when uploading or editing an image. For images in body fields, the CKEditor "Image Properties" dialog includes an Alt Text field.

Testomgeving

Voorgestelde oplossing

Hoe op te lossen: Associate every form control with a <label> (via for/id) or an aria-label/aria-labelledby.

Drupal-tip: Use Drupal's form element "Label" setting. In Webform, every element has a Label field — ensure it's not empty or hidden. Check that twig templates don't strip <label> elements from form fields.

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.

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 (1822 ruwe enginebevindingen → 1796 uniek).

Unieke problemen (regel × pagina): 1796
Door beide engines gevonden: 26 hoogste betrouwbaarheid
Alleen axe: 936
Alleen Alfa: 834

4 regeltype(n) door beide engines gevonden — hoogste betrouwbaarheid

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.

Regels die in 2026-W40 door zowel axe-core als Alfa zijn gemarkeerd, op getroffen pagina's.
