Accessibility

Understand how WCAG 2.2's four-principle architecture turns accessibility from a checklist into a coherent design discipline with measurable, legally-defensible outcomes.

Master every change in WCAG 2.2 — nine new success criteria, one removed, and the design implications that separate compliant interfaces from genuinely inclusive ones.

A deep look at where WCAG 3.0 stands in 2026, why its bronze/silver/gold scoring model is a seismic shift from binary pass/fail, and what practitioners should do right now.

Mastering semantic HTML and the browser's accessibility tree is the bedrock of inclusive interfaces — get this wrong and no ARIA patch will save you.

Knowing when — and when not — to reach for ARIA separates accessible components from fragile ones; the APG is your authoritative field guide.

Mastering keyboard navigation and the HTML `inert` attribute is what separates interfaces that merely look accessible from ones that actually work for keyboard and assistive-technology users.

Assistive technology isn't a niche edge case — understanding how real users navigate with screen readers, switches, and magnifiers unlocks the semantic rigor that makes every interface more robust.

Master perceptual principles and WCAG 2.2 contrast standards to design interfaces that communicate clearly for every human visual system.

Designing interfaces that work for people with memory, attention, and learning differences — grounded in W3C COGA guidance and WCAG 2.2 cognitive criteria.

Designing for the full range of human ability—permanent, temporary, and situational—produces better experiences for everyone, not just people with disabilities.

Purposeful motion elevates interfaces — but for millions of users with vestibular disorders, epilepsy, or sensory sensitivities, uncontrolled animation is a health hazard, not a delight.

Forms are where users transact — and inaccessible errors, missing labels, and broken validation flows silently exclude millions of people every day.

Cognitive barriers in login flows exclude millions of users — learn how WCAG 3.3.8 reshapes authentication design with passkeys, OTP autocomplete, and paste-friendly forms.

Properly sizing interactive controls prevents motor-skill errors and is now a legal baseline in WCAG 2.2 — learn exact thresholds, spacing mechanics, and implementation patterns.

Understand how the Americans with Disabilities Act, Section 508, and the EU Accessibility Act create legally binding accessibility obligations — and what WCAG conformance level satisfies each.

Automated tools catch roughly 30–40% of WCAG failures — understanding where that ceiling sits (and why) turns audit work into a disciplined, repeatable practice.
