skills/stitch-a11y/SKILL.mdStitch Accessibility Audit & Fix
You are an accessibility engineer. You audit components generated from Stitch designs, identify WCAG 2.1 AA violations, and apply fixes directly to the source files. You don't just report issues — you fix them.
Run this skill AFTER component generation. Components should be working before you audit them.
When to use this skill
Use this skill when:
- Components are generated and working, and need accessibility review before shipping
- The design has complex interactive patterns (modals, dropdowns, tab panels, accordions, carousels)
- The user mentions "accessibility", "a11y", "WCAG", "screen reader", "keyboard navigation"
- Preparing for a production launch or accessibility audit
Step 1: Discover components to audit
Read the project file structure to find all component files:
# Next.js / React find src -name "*.tsx" -not -path "*/node_modules/*" # SvelteKit find src -name "*.svelte" -not -path "*/node_modules/*"
Read each component file before auditing. Focus your energy on interactive components — static content needs less attention than forms, navigation, modals, and dropdowns.
Step 2: The audit — 6 categories
Work through each category systematically for every component.
Category 1: Semantic HTML
Violations to find:
or<div>
used for navigation, headers, footers, main content, articles, sections<span>
instead of<div onClick>
or<button><a>- Heading hierarchy out of order (h3 before h2, skipping levels)
- Tables used for layout (not data)
- Lists rendered as plain
elements<div>
Fixes:
// ❌ Wrong <div className="nav"> <div onClick={goHome}>Home</div> </div> // ✅ Fixed <nav aria-label="Main navigation"> <a href="/">Home</a> </nav> // ❌ Wrong — div button <div className="btn" onClick={handleClick}>Submit</div> // ✅ Fixed — real button <button type="button" onClick={handleClick}>Submit</button> // ❌ Wrong — visual list as divs <div className="menu"> <div>Item 1</div> <div>Item 2</div> </div> // ✅ Fixed <ul role="list"> <li>Item 1</li> <li>Item 2</li> </ul>
Category 2: ARIA attributes
Only add ARIA where semantic HTML doesn't provide sufficient information. Remember: no ARIA is better than bad ARIA.
Violations to find:
- Icon-only buttons with no accessible name
- Multiple
landmarks with no<nav>aria-label - Multiple
elements<main> - Status/live regions that update dynamically but have no
aria-live - Interactive elements missing
,aria-expanded
,aria-haspopuparia-controls
Fixes:
// Icon-only button <button aria-label="Close dialog" type="button"> <XIcon aria-hidden="true" /> </button> // Multiple nav regions <nav aria-label="Main navigation">...</nav> <nav aria-label="Breadcrumb">...</nav> <nav aria-label="Pagination">...</nav> // Dropdown toggle <button aria-expanded={isOpen} aria-haspopup="menu" aria-controls="user-menu" > Account </button> <ul id="user-menu" role="menu" hidden={!isOpen}> <li role="menuitem"><a href="/profile">Profile</a></li> </ul> // Live status region <div aria-live="polite" aria-atomic="true" className="sr-only"> {statusMessage} </div>
Category 3: Keyboard navigation
Every interactive element must be operable by keyboard. Test this mental model: Tab through the page — can you reach and activate every action?
Violations to find:
- Custom interactive elements that don't receive Tab focus
used where focus should be reachabletabIndex={-1}
or higher (breaks natural tab order)tabIndex={1}- Modal open — focus not moved into modal
- Modal closed — focus not returned to trigger
- Dropdown closed with Escape — focus not returned
Fixes:
// Focus management for modal — React import { useEffect, useRef } from 'react' export function Modal({ isOpen, onClose, children }: ModalProps) { const modalRef = useRef<HTMLDivElement>(null) const triggerRef = useRef<HTMLButtonElement>(null) useEffect(() => { if (isOpen) { // Move focus into modal when it opens modalRef.current?.focus() } }, [isOpen]) function handleClose() { onClose() // Return focus to trigger when modal closes triggerRef.current?.focus() } return ( <> <button ref={triggerRef} onClick={() => setIsOpen(true)}> Open Modal </button> {isOpen && ( <div ref={modalRef} role="dialog" aria-modal="true" aria-labelledby="modal-title" tabIndex={-1} /* Makes div focusable without entering tab order */ > <h2 id="modal-title">Modal Title</h2> {children} <button onClick={handleClose}>Close</button> </div> )} </> ) } // Keyboard handler for custom interactive elements <div role="button" tabIndex={0} onClick={handleAction} onKeyDown={(e) => { if (e.key === 'Enter' || e.key === ' ') { e.preventDefault() handleAction() } }} > Custom button behavior </div>
<!-- Focus management in Svelte --> <script lang="ts"> let dialogEl = $state<HTMLDialogElement>() let triggerEl = $state<HTMLButtonElement>() let isOpen = $state(false) function openDialog() { isOpen = true // tick() ensures DOM is updated before focusing tick().then(() => dialogEl?.focus()) } function closeDialog() { isOpen = false triggerEl?.focus() // Return focus to trigger } </script> <button bind:this={triggerEl} onclick={openDialog}>Open</button> {#if isOpen} <dialog bind:this={dialogEl} tabindex="-1" aria-modal="true" onkeydown={(e) => e.key === 'Escape' && closeDialog()} > <button onclick={closeDialog}>Close</button> </dialog> {/if}
Category 4: Focus visibility
Every interactive element must have a visible focus indicator. Never remove the focus ring without providing an equally visible replacement.
Violations to find:
oroutline: none
without a custom focus styleoutline: 0
in Tailwind without.focus:outline-nonefocus-visible:ring-*- Focus styles that only appear on click, not keyboard focus
Fixes:
In CSS:
/* Never this */ *:focus { outline: none; } /* Always this — uses :focus-visible to show only on keyboard focus */ *:focus-visible { outline: 2px solid var(--color-primary); outline-offset: 2px; border-radius: 2px; }
In Tailwind:
// ❌ Wrong <button className="focus:outline-none"> // ✅ Fixed <button className="focus:outline-none focus-visible:ring-2 focus-visible:ring-primary focus-visible:ring-offset-2">
Category 5: Images and media
Violations to find:
or<img>
without<Image>
attributealt- Meaningful images with
alt="" - Decorative images with descriptive alt text (adds noise to screen readers)
- Icons without accessible labels when used as interactive elements
- Video without captions
Fixes:
// Meaningful image <Image src="/hero.jpg" alt="Team members collaborating at a whiteboard in a modern office" /> // Decorative image — empty alt so screen readers skip it <Image src="/bg-pattern.svg" alt="" aria-hidden="true" /> // Icon in a button — hide icon, label the button <button aria-label="Delete item"> <TrashIcon aria-hidden="true" /> </button> // Icon with adjacent text — hide the icon (it's redundant) <button> <SaveIcon aria-hidden="true" /> <span>Save changes</span> </button>
Category 6: Color and contrast
Check these without automated tools by reasoning about the design:
Violations to find:
- Muted text (
) on a muted background (--color-text-muted
) — often fails 4.5:1--color-surface - Primary color on white at small sizes — verify it passes 4.5:1
- Disabled state text that's too light to read even as a hint
- Relying on color alone to convey meaning (error states, required fields)
Fixes:
// Add non-color indicator for errors <input aria-invalid={hasError} aria-describedby={hasError ? 'email-error' : undefined} className={hasError ? 'border-error' : 'border-border'} /> {hasError && ( <p id="email-error" role="alert" className="text-error"> {/* Icon + text — not color alone */} <AlertIcon aria-hidden="true" /> Please enter a valid email address </p> )} // Required field indicator <label> Email <span aria-hidden="true" className="text-error"> *</span> <span className="sr-only">(required)</span> </label>
Step 3: The sr-only
utility class
sr-onlyAdd this to your global CSS if it's not there already. You'll use it frequently:
/* Visually hidden, but readable by screen readers */ .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; } /* Skip link — visible on focus for keyboard users */ .skip-link { position: absolute; left: -9999px; top: auto; width: 1px; height: 1px; overflow: hidden; } .skip-link:focus { position: fixed; top: 1rem; left: 1rem; width: auto; height: auto; padding: 0.5rem 1rem; background: var(--color-primary); color: var(--color-primary-fg); border-radius: var(--radius-md); font-weight: 600; z-index: 9999; }
Step 4: Skip navigation link
Add a skip link as the first element in every page layout. This lets keyboard users jump past the navigation:
// app/layout.tsx or +layout.svelte — first child of <body> <a href="#main-content" className="skip-link"> Skip to main content </a> // The target <main id="main-content" tabIndex={-1}> {children} </main>
Step 5: Generate the audit report
After fixing, create
accessibility-audit.md summarizing what was found and fixed:
# Accessibility Audit Report **Date:** [date] **WCAG Target:** 2.1 AA **Components audited:** [list] ## Issues Found & Fixed ### Critical (would block screen reader users) - [Component]: [issue] → [fix applied] ### Important (keyboard navigation issues) - [Component]: [issue] → [fix applied] ### Minor (improvements to quality of life) - [Component]: [issue] → [fix applied] ## Remaining Recommendations [Any issues that require design changes or user testing to resolve] ## How to test 1. Tab through the entire page — every interactive element should be reachable 2. Activate with Enter/Space — all buttons and links should work 3. Test with VoiceOver (Mac) or NVDA (Windows) — key flows should be narrated correctly 4. Browser DevTools → Rendering → Emulate prefers-reduced-motion → Verify animations stop 5. axe DevTools extension for automated checks
Troubleshooting
| Issue | Fix |
|---|---|
points to wrong ID | Ensure IDs are unique across the page |
| Focus trap locking keyboard in modal | Implement proper Tab/Shift+Tab cycling within modal bounds |
| Screen reader announcing redundant info | Add to decorative elements |
| Multiple violations in one component | Fix semantic HTML first — ARIA issues often cascade from it |
| Skip link not showing | Ensure state overrides the off-screen positioning |
