Stitch 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:

• <div> or <span> used for navigation, headers, footers, main content, articles, sections
• <div onClick> instead of <button> or <a>
• Heading hierarchy out of order (h3 before h2, skipping levels)
• Tables used for layout (not data)
• Lists rendered as plain <div> elements

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 <nav> landmarks with no aria-label
• Multiple <main> elements
• Status/live regions that update dynamically but have no aria-live
• Interactive elements missing aria-expanded, aria-haspopup, aria-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
• tabIndex={-1} used where focus should be reachable
• tabIndex={1} or higher (breaks natural tab order)
• 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:

• outline: none or outline: 0 without a custom focus style
• .focus:outline-none in Tailwind without focus-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:

• <img> or <Image> without alt attribute
• 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 (--color-text-muted) on a muted background (--color-surface) — often fails 4.5:1
• 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-describe
