---

Phase 3: Semantic HTML & ARIA Cheat Sheet

Landmark Roles (use HTML5 elements, not role attributes when possible)

<header>     → banner (page header)
<nav>        → navigation
<main>       → main content (one per page)
<aside>      → complementary
<footer>     → contentinfo (page footer)
<section>    → region (with aria-label)
<form>       → form (with aria-label)
<search>     → search

Common ARIA Patterns

Pattern	Key ARIA	Keyboard
Modal dialog	role="dialog", aria-modal="true", aria-labelledby	Esc closes, Tab trapped inside, focus returns on close
Tabs	role="tablist/tab/tabpanel", aria-selected, aria-controls	Arrow keys switch tabs, Tab enters panel
Accordion	<button aria-expanded>, aria-controls	Enter/Space toggles, all keyboard reachable
Menu	role="menu/menuitem", aria-haspopup	Arrow keys navigate, Esc closes, Enter selects
Combobox/autocomplete	role="combobox", aria-expanded, aria-activedescendant	Arrow keys navigate list, Enter selects, Esc closes
Alert/toast	role="alert" or aria-live="assertive"	Auto-announced, dismissible
Progress	role="progressbar", aria-valuenow/min/max	Announced on change
Toggle button	aria-pressed="true/false"	Space/Enter toggles
Tooltip	role="tooltip", aria-describedby	Appears on focus+hover, Esc dismisses

ARIA Rules of Engagement

1. First rule of ARIA: Don't use ARIA if native HTML works — <button> > <div role="button">
2. Second rule: Don't change native semantics — Don't <h2 role="tab">
3. Third rule: All interactive ARIA controls must be keyboard accessible
4. Fourth rule: Don't use role="presentation" or aria-hidden="true" on focusable elements
5. Fifth rule: All interactive elements must have an accessible name

Accessible Name Priority (browser resolution order)

1. aria-labelledby (references another element's text)
2. aria-label (string label)
3. <label> association (for form controls)
4. Contents (button text, link text)
5. title attribute (last resort — avoid)
6. placeholder (NOT a label — supplementary only)

Phase 4: Testing Methodology

4-Layer Testing Pyramid

Layer 1: Automated Scanning (catches ~30% of issues)

Run on EVERY build/PR:

Tools (all free):

• axe-core — industry standard, lowest false positives

  # In Playwright/Cypress
  npm install @axe-core/playwright  # or @axe-core/cypress
  # In CI
  npm install @axe-core/cli
  axe https://your-site.com --tags wcag2a,wcag2aa
  

• Lighthouse — Chrome DevTools → Lighthouse → Accessibility
• WAVE — wave.webaim.org (visual overlay)
• Pa11y — CLI scanner for CI pipelines

  pa11y https://your-site.com --standard WCAG2AA
  

CI pipeline integration:

# GitHub Actions example
a11y-test:
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@v4
    - run: npm ci && npm run build
    - run: npx pa11y-ci --config .pa11yci.json
    - run: npx playwright test --grep @a11y

Layer 2: Keyboard Testing (catches navigation issues)

Test EVERY page/feature manually:

1. Tab test: Tab through entire page — can you reach everything? Is order logical?
2. Focus visibility test: Is the focus indicator always visible and clear?
3. Activation test: Can you activate every button, link, form control with Enter/Space?
4. Trap test: Can you always Tab or Esc out of components (modals, menus)?
5. Skip link test: Does "Skip to main content" work?

Keyboard testing checklist per page:

keyboard_test:
  page: ""
  date: ""
  tester: ""
  results:
    all_interactive_reachable: true/false
    logical_tab_order: true/false
    focus_always_visible: true/false
    no_keyboard_traps: true/false
    skip_link_works: true/false
    custom_components_keyboard_operable: true/false
  issues: []

Layer 3: Screen Reader Testing (catches semantic issues)

Test key flows with at least ONE screen reader:

Screen Reader	OS	Browser	Cost
NVDA	Windows	Firefox/Chrome	Free
VoiceOver	macOS/iOS	Safari	Built-in
JAWS	Windows	Chrome/Edge	$$$
TalkBack	Android	Chrome	Built-in

Essential screen reader checks:

1. Page structure announced (headings, landmarks, lists)
2. Images described (or correctly hidden if decorative)
3. Forms: labels read, errors announced, required fields indicated
4. Dynamic content announced (alerts, loading states, live regions)
5. Custom components: role, name, state all announced

Quick VoiceOver test (macOS):

• Cmd+F5 to toggle
• VO+Right arrow to navigate
• VO+U for rotor (headings, links, landmarks)
• Tab for interactive elements only

Layer 4: Manual Expert Review (catches context & usability issues)

Quarterly or before major releases:

• Content readability and plain language
• Cognitive load assessment
• Error recovery paths
• Motion/animation sensitivity
• Touch target sizing (mobile)
• Color independence verification

Testing Priority Matrix

Page/Feature	Auto	Keyboard	Screen Reader	Expert
Homepage	Every build	Monthly	Quarterly	Annually
Login/Signup	Every build	Monthly	Quarterly	Annually
Checkout/Payment	Every build	Weekly	Monthly	Quarterly
Search	Every build	Monthly	Quarterly	Annually
Forms (all)	Every build	Monthly	Monthly	Quarterly
New features	Before ship	Before ship	Before ship	Major only

Phase 5: Common Fix Patterns

Fix 1: Missing alt text

<!-- ❌ -->
<img src="chart.png">
<img src="decorative-swoosh.svg">

<!-- ✅ -->
<img src="chart.png" alt="Revenue grew 34% from $1.8M to $2.4M in Q3 2025">
<img src="decorative-swoosh.svg" alt="" role="presentation">

Fix 2: Color-only indicators

<!-- ❌ Error shown only by red border -->
<input style="border-color: red">

<!-- ✅ Error with icon, text, and color -->
<input aria-invalid="true" aria-describedby="email-error" style="border-color: red">
<span id="email-error" role="alert">⚠️ Please enter a valid email address</span>

Fix 3: Custom button

<!-- ❌ Div pretending to be a button -->
<div class="btn" onclick="submit()">Submit</div>

<!-- ✅ Just use a button -->
<button type="submit">Submit</button>

<!-- ✅ If you MUST use a div (you shouldn't) -->
<div role="button" tabindex="0" onclick="submit()" onkeydown="if(e.key==='Enter'||e.key===' ')submit()">Submit</div>

Fix 4: Form labels

<!-- ❌ Placeholder-only label -->
<input placeholder="Email address">

<!-- ✅ Visible label -->
<label for="email">Email address</label>
<input id="email" type="email" autocomplete="email" placeholder="[e-mail]">

<!-- ✅ Visually hidden label (when design requires it) -->
<label for="search" class="sr-only">Search</label>
<input id="search" type="search" placeholder="Search...">

Fix 5: Focus management (SPA route changes)

// After client-side navigation:
// 1. Update document.title
document.title = `${newPageName} | Site Name`;

// 2. Move focus to main content or h1
const main = document.querySelector('main h1') || document.querySelector('main');
main.setAttribute('tabindex', '-1');
main.focus();

// 3. Announce to screen readers
const announcer = document.getElementById('route-announcer');
announcer.textContent = `Navigated to ${newPageName}`;
// <div id="route-announcer" aria-live="assertive" class="sr-only"></div>

Fix 6: Modal focus trap

function trapFocus(modal) {
  const focusable = modal.querySelectorAll(
    'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
  );
  const first = focusable[0];
  const last = focusable[focusable.length - 1];

  modal.addEventListener('keydown', (e) => {
    if (e.key === 'Escape') { closeModal(); return; }
    if (e.key !== 'Tab') return;
    if (e.shiftKey && document.activeElement === first) {
      e.preventDefault(); last.focus();
    } else if (!e.shiftKey && document.activeElement === last) {
      e.preventDefault(); first.focus();
    }
  });

  first.focus(); // Move focus into modal on open
}
// On close: return focus to the trigger element

Fix 7: Live region for dynamic content

<!-- Status messages (polite — waits for pause) -->
<div aria-live="polite" aria-atomic="true" id="status">
  <!-- JS updates: "3 results found", "Item added to cart" -->
</div>

<!-- Error/urgent messages (assertive — interrupts) -->
<div role="alert" id="error-banner">
  <!-- JS updates: "Payment failed. Please try again." -->
</div>

CSS: Visually Hidden (screen reader only)

.sr-only {
  position: absolute;
  width: 1px;
  height: 1px;
  padding: 0;
  margin: -1px;
  overflow: hidden;
  clip: rect(0, 0, 0, 0);
  white-space: nowrap;
  border-width: 0;
}

Phase 6: Design System Accessibility Standards

Color Contrast Requirements

Tools for checking:

• Colour Contrast Analyser (desktop app)
• WebAIM Contrast Checker (webaim.org/resources/contrastchecker)
• Stark (Figma plugin)

Minimum ratios:

Element	WCAG AA	WCAG AAA
Normal text (<18pt)	4.5:1	7:1
Large text (≥18pt or ≥14pt bold)	3:1	4.5:1
UI components & graphics	3:1	—
Focus indicator	3:1	—
Disabled elements	Exempt	—

Touch Target Sizing

Standard	Minimum Size	Spacing
WCAG 2.5.8 (AAA)	44×44 CSS px	—
WCAG 2.5.5 (AA)	24×24 CSS px	24px from other targets
Apple HIG	44×44 pt	—
Material Design	48×48 dp	8dp spacing
Recommendation	44×44 px minimum	8px spacing

Typography Accessibility

• Base font size: 16px minimum (body text)
• Line height: 1.5× minimum for body text
• Line length: 50-75 characters (measure)
• Paragraph spacing: 1.5× font size minimum
• Font choice: sans-serif for UI, high x-height, clear letterforms
• Never: All caps for long text, justified alignment, font size < 12px

Animation & Motion

/* Respect user preference */
@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
    scroll-behavior: auto !important;
  }
}

• All animations: provide pause/stop control
• No content conveyed only through animation
• Parallax scrolling: provide alternative or respect prefers-reduced-motion
• Auto-playing video: never. User-initiated only.

Dark Mode Accessibility

• Re-check ALL contrast ratios in dark mode (common failure point)
• Don't just invert — pure white (#fff) on dark backgrounds causes halation
• Use off-white (#e0e0e0 to #f0f0f0) on dark backgrounds
• Colored text: re-verify contrast on dark backgrounds
• Images: consider transparent PNGs on dark backgrounds

---

Phase 7: Component Accessibility Specifications

For each common component, specify the complete accessible behavior:

Button

semantics: "<button> or role='button'"
accessible_name: "visible text or aria-label"
keyboard:
  - "Enter/Space: activate"
states:
  - "aria-disabled='true' (not HTML disabled — that removes from tab order)"
  - "aria-pressed for toggles"
  - "aria-expanded for menus/dropdowns"
notes:
  - "Never use <a> for actions (buttons do things, links go places)"
  - "Loading state: aria-busy='true', disable click, announce 'Loading...'"

Form Field

required:
  - "Visible <label> with for= attribute"
  - "Error message with aria-describedby"
  - "Required indicator: aria-required='true' + visible '(required)' or '*' with legend"
  - "autocomplete attribute for user data fields"
keyboard:
  - "Tab to reach, type to fill"
  - "Error: focus moves to first error field on submit"
validation:
  - "Inline validation: after blur, not on every keystroke"
  - "Error format: What went wrong + how to fix it"
  - "Success: subtle confirmation, no modal"
group:
  - "Related fields: <fieldset> + <legend> (radio groups, address blocks)"

Data Table

required:
  - "<table>, <thead>, <tbody>, <th scope='col/row'>"
  - "<caption> describing the table"
  - "Complex tables: headers= attribute on <td>"
keyboard:
  - "Sortable: button in <th>, aria-sort='ascending/descending/none'"
  - "Pagination: standard button/link navigation"
responsive:
  - "Small screens: horizontal scroll with sticky first column, or card layout"
  - "Never hide columns without providing access to that data"
avoid:
  - "Layout tables (use CSS grid/flex)"
  - "Nested tables"

Navigation

required:
  - "<nav aria-label='Main'> (label if multiple navs)"
  - "Current page: aria-current='page'"
  - "Skip link as first focusable element"
keyboard:
  - "Tab to enter, Tab through items"
  - "Dropdown menus: Enter/Space to open, Arrow keys to navigate, Esc to close"
mobile:
  - "Hamburger: <button aria-expanded='false' aria-controls='menu-id'>"
  - "Update aria-expanded on toggle"

Phase 8: Accessibility Scoring Rubric (0-100)

Dimension	Weight	0-25	50	75	100
Automated scan	15%	50+ violations	20-49	5-19	0 critical/serious
Keyboard navigation	20%	Major traps, unreachable elements	Most works, some gaps	All reachable, minor focus issues	Perfect tab order, visible focus, no traps
Screen reader compat	20%	Unusable (missing labels, roles)	Partially navigable	Mostly correct, minor omissions	Full landmark/heading/label coverage
Color & contrast	10%	Multiple failures	Some failures	Mostly passing	All elements ≥ AA ratios
Forms & errors	15%	Unlabeled, no error handling	Labels exist, errors unclear	Good labels, some error gaps	Full labels, inline errors, suggestions
Content structure	10%	No heading hierarchy, no landmarks	Partial hierarchy	Good structure, minor gaps	Perfect heading levels, complete landmarks
Dynamic content	10%	No live regions, modals trap	Some announcements	Most dynamic content announced	All state changes properly announced

Scoring thresholds:

• 90-100: Audit-ready. Maintain with automated testing.
• 70-89: Good foundation. Fix remaining issues within 30 days.
• 50-69: Significant gaps. Prioritize critical/serious issues.

Phase 12: Advanced Patterns

Cognitive Accessibility (WCAG 2.2 / COGA)

• Clear, simple language (aim for 8th grade reading level)
• Consistent navigation and layout
• Error prevention > error recovery
• Undo for destructive actions
• No time pressure unless essential
• Progress indicators for multi-step processes
• Help available on every page

Internationalization & Accessibility

• dir="rtl" for right-to-left languages
• Don't concatenate translated strings (word order varies)
• Number/date formatting: use Intl API
• Currency symbols: position varies by locale
• Test with longer text (German is ~30% longer than English)

PDF Accessibility

• Tag all content (headings, paragraphs, lists, tables, images)
• Reading order matches visual order
• Alt text on all images
• Language specified
• Bookmarks for navigation
• Tool: PAC (PDF Accessibility Checker) — free

Email Accessibility

• role="presentation" on layout tables
• Inline styles (not external CSS)
• alt on all images (including spacer GIFs: alt="")
• Sufficient color contrast (check in dark mode too)
• Plain text version always available
• Semantic headings (<h1>, <h2>)
• Link text descriptive (not "click here")
