Deep divePro

a11y.quest is a self-paced quiz tool built around 128 accessibility questions covering WCAG 2.2 criteria, ARIA usage, semantic HTML, keyboard navigation, and contrast — all answered in plain English rather than spec-speak. It's essentially a flashcard system for designers and developers who know they should understand accessibility better but find the official documentation impenetrable. The core value is translating dry compliance standards into digestible, testable knowledge you can actually retain.

Why it stands out

The plain-English answer format is doing real work here — most WCAG resources read like legal documents, and this tool specifically targets the comprehension gap between 'I've heard of WCAG' and 'I can defend a design decision in a review.' Covering contrast, ARIA, and keyboard behavior in one place makes it unusually broad for a quiz tool.

Best for

Generalist designers who are starting to get pulled into accessibility audits or handoff conversations and need to build fluency fast without wading through the full W3C spec.
