fix: WCAG 2.1 AA accessibility audit — contrast fixes, ARIA labels, keyboard nav, mobile a11y & ACCESSIBILITY.md by Itzzavdheshh · Pull Request #388 · Dev-Card/DevCard

Summary

Conducts a complete WCAG 2.1 AA accessibility audit across apps/web and apps/mobile as specified in Product Doc Section 5.11 — zero prior accessibility work existed. Fixes all AA-level color contrast failures, adds missing ARIA labels on icon-only buttons, strengthens invisible focus rings, adds skip navigation, completes all mobile accessibilityLabel/accessibilityRole/accessibilityHint attributes, describes QR codes for screen readers, extends font size tokens to prevent inline hardcoding, and documents everything in a new ACCESSIBILITY.md. Also fixes a pre-existing duplicate import bug in SettingsScreen.tsx.

Closes #39

Type of Change

What Changed

apps/web/src/app.css

--text-muted light: #64748b → #536071 — passes 4.5:1 on white
--text-secondary light: #475569 → #334155 — passes 4.5:1
.copy-message.error: #ef4444 → #dc2626 — passes 4.5:1 on white
All focus-visible outlines: near-invisible rgba(..., 0.18–0.35) → solid 3px solid #6366f1
.role-badge, .card-footer, .username on dark card — contrast verified ≥ 4.5:1

apps/web/src/routes/+layout.svelte

Visually-hidden skip-to-main-content link added — appears on keyboard focus, href="#main-content"

apps/web/src/routes/+page.svelte (homepage)

Theme toggle: aria-label="Toggle dark mode" — was emoji-only 🌙/☀️
<main id="main-content"> + <nav aria-label="Main navigation"> added

apps/web/src/routes/u/[username]/+page.svelte

Links section: <section aria-label="Platform connections"> added
"Copy Link" button: aria-label added; aria-live="polite" region confirmed

apps/web/src/routes/devcard/[id]/+page.svelte

Platform buttons: aria-label="{platform} — {username}, opens in new tab" on each
<section aria-label="Platform Connections"> + <main> wrapper added

apps/mobile/src/screens/DevCardViewScreen.tsx

Close button, platform tiles, error back button — accessibilityLabel + accessibilityRole="button" + accessibilityHint added
QR code: accessible={true} + accessibilityRole="image" + descriptive label

apps/mobile/src/screens/HomeScreen.tsx

QR toggle, Share, Analytics, Preview, Search Go — all get accessibilityLabel + accessibilityRole="button"
QR toggle: accessibilityHint="Double-tap to toggle QR code visibility"
TextInput: accessibilityLabel="Enter DevCard username"

apps/mobile/src/screens/ScanScreen.tsx

Switch Card, Go button, QR container, TextInput — all accessibility attributes added
Switch Card: accessibilityHint="Opens a list of your DevCards to choose which to display"

apps/mobile/src/screens/SettingsScreen.tsx

Connected Platforms, Save Changes, Log Out, all TextInputs — accessibilityLabel + accessibilityRole added
Pre-existing bug fixed: duplicate import { useNavigation } on lines 14 and 19 removed

apps/mobile/src/theme/tokens.ts

FONT_SIZE.micro = 10 and FONT_SIZE.nano = 8 added — inline fontSize: 8/9/10 now use tokens
Comment added: allowFontScaling={false} must never be used — dynamic type scaling preserved

ACCESSIBILITY.md (NEW)

Full audit grouped by page and severity with resolution status
Screen reader navigation walkthrough for "View a DevCard" flow
Future contributor guidelines for contrast, ARIA, and mobile a11y

How to Test

# Web
cd apps/web && pnpm dev
# Install axe DevTools browser extension → run on /, /u/[username], /devcard/[id]

# Typecheck
pnpm -r run typecheck

# Lint
pnpm -r run lint

# Mobile
cd apps/mobile && pnpm start

Press Tab on homepage → verify skip link appears → press Enter → focus jumps to #main-content
Tab to theme toggle → verify aria-label="Toggle dark mode" announced by screen reader
Tab through all web pages → verify solid 3px focus ring visible on every interactive element
Run axe DevTools on /, /u/[username], /devcard/[id] → verify zero AA violations
Open /u/[username] → click "Copy Link" → verify aria-live region announces success
Open /devcard/[id] → tab to platform buttons → verify label reads "{platform} — {username}, opens in new tab"
On mobile: navigate DevCardViewScreen with TalkBack/VoiceOver → verify all buttons announced with label + role
On mobile: verify QR code announced as "image" with descriptive label
On mobile: increase system font size to 150% → verify all text scales correctly (no clipping)
Run pnpm -r run typecheck → verify zero errors after duplicate import fix

Checklist

Screenshots / Recordings

1. Before — near-invisible focus ring

2. After — solid 3px focus ring

2. axe DevTools — zero AA violations on /

3. axe DevTools — zero AA violations on /u/[username]

4. Skip link visible on first Tab keypress

Additional Context

Why #536071 not #475569 for --text-muted? The fix targets the minimum ratio (4.5:1) while staying visually close to the original. #475569 would also pass but is harder to distinguish from --text-secondary — using #536071 keeps the two tokens visually separated.
Screen reader device testing: TalkBack/VoiceOver testing requires a physical Android/iOS device. Code correctness is verified; expected screen reader behavior is documented in ACCESSIBILITY.md. This is the standard approach for code-level a11y reviews without a device.
@axe-core/playwright CI: Not added in this PR to keep scope focused. ACCESSIBILITY.md documents the integration path for a follow-up PR.
socket.io-client and large asset optimization are tracked as separate issues — out of scope here.
Future work: Add @axe-core/playwright automated CI check; audit any new pages added after this PR against the guidelines in ACCESSIBILITY.md.

Hi @Itzzavdheshh, will not be using Expo for any functionality, so please do not include that in the devcard.

Hi @ShantKhatri! Understood on not using Expo for product features.

Right now, Expo is only used as a developer helper in the background to dynamically resolve local IP addresses for testing the app locally. We aren't using any of the main Expo SDK features.

Would you still like me to completely remove these helper packages and rewrite the configurations, or is it fine to keep them just for local development convenience?

We need to remove the expo completely and rewrite the configuration. As that breaks our functionalities or makes the configuration break when we try to deal with it natively. Thanks!
