A lot of accessibility content stops at the design layer — contrast ratios, font sizing, layout. Aufait UX's ADA compliance guide is a useful reminder that a meaningful chunk of WCAG 2.1 AA conformance is implementation-level, not visual.
What needs to hold up in the actual build
Semantic HTML and ARIA roles — screen readers depend on correct structure, not just correct appearance. A visually perfect component built on generic soup will still fail accessibility testing.
Keyboard operability — every interactive element needs to be reachable and usable without a mouse, which often surfaces gaps in custom components (custom dropdowns, modals, date pickers) that look fine but trap focus or break tab order.
Accessible PDFs — frequently shipped as flat scanned documents with zero structure for assistive tech, a compliance gap that's easy to miss because PDFs don't get the same QA attention as the main site.
Video captions and audio descriptions — required for both Section 508 and ADA-aligned compliance, not optional polish, and easy to deprioritize under deadline pressure.
Why automated testing isn't enough
One stat from the piece worth internalizing: automated accessibility scanners typically catch only 30–40% of real barriers. The rest requires manual testing — actually navigating the product with a screen reader, actually tabbing through every interactive flow. Teams that rely solely on a Lighthouse score or an automated scanner are shipping with a false sense of compliance.
Where this fits into the dev workflow
For dev teams working alongside web ui design services, this is a good reminder that accessibility QA needs to happen at the code review level, not just the design review stage — a beautifully accessible Figma file can still ship a non-compliant build if implementation details (focus order, ARIA labeling, semantic structure) get missed during development. Building an accessibility checklist into PR review, the same way teams handle security or performance review, is the practical fix the guide points toward implicitly.
Also worth noting for teams offering ui design solutions to clients: litigation volume around ADA Title III continues to climb year over year, which makes accessibility increasingly a risk-management conversation for clients, not just a design preference.
