+
++ aria-haspopup="listbox"
+
+- aria-label="clear value"
++ aria-label={`Clear ${label ?? 'selection'}`}
+
+-
++
+```
+
+**Impact**: SelectInput now has proper combobox ARIA attributes.
+
+---
+
+### 7. Slider Component
+**Files**:
+- `packages/ui/src/components/Slider/components/SingleSlider.tsx`
+- `packages/ui/src/components/Slider/components/DoubleSlider.tsx`
+
+**Issues Fixed**:
+- ❌ Missing `aria-valuemin`, `aria-valuemax`, `aria-valuenow`
+- ❌ Missing `aria-valuetext` for better screen reader announcements
+- ❌ Generic `aria-label="input"`
+
+**Changes Made**:
+```diff
+
+
+ // For double slider
++ aria-label={`${ariaLabel ?? name} minimum`}
++ aria-valuetext={`${selectedIndexes[0]}${...}`}
+
++ aria-label={`${ariaLabel ?? name} maximum`}
++ aria-valuetext={`${selectedIndexes[1]}${...}`}
+```
+
+**Impact**: Slider values are now properly announced to screen readers.
+
+---
+

+7. **FileInput** - Add keyboard alternatives for drag-and-drop
+8. **ExpandableCard** - Add `aria-expanded` to summary
+9. **Checkbox/Radio** - Remove redundant `aria-disabled` from wrappers
+10. **Color Contrast** - Audit all color combinations
+
+### Recommended Actions:
+
+1. **Update Tests**: Add axe-core tests to all component test suites
+2. **Update Documentation**: Add accessibility sections to all component docs
+3. **Create Examples**: Show accessible usage patterns in Storybook stories
+4. **Linting Rules**: Enable all jsx-a11y ESLint rules
+5. **CI Integration**: Add accessibility testing to CI pipeline
+
+## 📝 Testing Recommendations
+
+Add this test pattern to all component tests:
+
+```tsx
+import { axe } from 'axe-core'
+import { expect } from 'vitest'
+import { render } from '@testing-library/react'
+
+describe('Accessibility', () => {
+ it('should have no accessibility violations', async () => {
+ const { container } = render(
)
+ const results = await axe(container)
+ expect(results).toHaveNoViolations()
+ })
+})
+```
+
+## 🎯 Impact
+
+These fixes significantly improve the accessibility of the Ultraviolet design system, making it more usable for:
+- Keyboard-only users
+- Screen reader users
+- Users with motor impairments
+- Users with visual impairments
+- Users with cognitive disabilities
+
+All changes maintain backward compatibility while improving accessibility compliance to WCAG 2.1 AA standards.

+# Accessibility Guidelines for Ultraviolet
+
+This document provides guidelines and patterns for building accessible components in the Ultraviolet design system.
+
+## 🎯 Core Principles
+
+1. **Perceivable**: Information and user interface components must be presentable to users in ways they can perceive
+2. **Operable**: User interface components and navigation must be operable by all users
+3. **Understandable**: Information and the operation of user interface must be understandable
+4. **Robust**: Content must be robust enough to be interpreted by a wide variety of user agents, including assistive technologies
+
+## 📝 Development Guidelines
+
+### 1. Use Semantic HTML
+
+Always prefer native HTML elements over custom components when possible:
+
+```tsx
+// ✅ Good - uses native button
+
Click me
+
+// ❌ Bad - requires additional ARIA
+
Click me
+```
+
+### 2. Provide Accessible Names
+
+All interactive elements must have accessible names:
+
+```tsx
+// ✅ Good - has accessible name
+
+
+
+
+// ❌ Bad - no accessible name
+
+
+
+```
+
+### 3. Manage Focus Properly
+
+Ensure focus is visible and managed correctly:
+
+```tsx
+// ✅ Good - focus returns to trigger
+const handleOpen = () => {
+ setIsOpen(true)
+ triggerRef.current?.focus()
+}
+
+const handleClose = () => {
+ setIsOpen(false)
+ triggerRef.current?.focus()
+}
+```
+
+### 4. Support Keyboard Navigation
+
+All interactive components must be keyboard accessible:
+
+```tsx
+// ✅ Good - handles keyboard events
+
{
+ if (e.key === 'ArrowDown') {
+ e.preventDefault()
+ focusNextItem()
+ }
+ if (e.key === 'ArrowUp') {
+ e.preventDefault()
+ focusPreviousItem()
+ }
+ if (e.key === 'Escape') {
+ closeMenu()
+ }
+ }}
+>
+ {items}
+
+```
+
+### 5. Use ARIA Correctly
+
+ARIA should enhance, not replace, native semantics:
+
+```tsx
+// ✅ Good - proper ARIA usage
+
+```
+
+## 🧩 Component Patterns
+
+### Buttons
+
+```tsx
+type ButtonProps = {
+ children: ReactNode
+ onClick?: () => void
+ disabled?: boolean
+ 'aria-label'?: string
+ 'aria-pressed'?: boolean // for toggle buttons
+ 'aria-expanded'?: boolean // for buttons that control visibility
+}
+
+export const Button = ({
+ children,
+ onClick,
+ disabled,
+ 'aria-label': ariaLabel,
+ 'aria-pressed': ariaPressed,
+ 'aria-expanded': ariaExpanded,
+}: ButtonProps) => (
+
+ {children}
+
+)
+```
+
+### Links
+
+```tsx
+type LinkProps = {
+ href: string
+ target?: '_blank' | '_self' | '_parent' | '_top'
+ children: ReactNode
+ 'aria-label'?: string
+ 'aria-current'?: 'page' | 'step' | 'location' | 'date' | 'time' | 'true' | 'false'
+}
+
+export const Link = ({
+ href,
+ target,
+ children,
+ 'aria-label': ariaLabel,
+ 'aria-current': ariaCurrent,
+}: LinkProps) => {
+ const isExternal = target === '_blank'
+
+ return (
+
+ {children}
+ {isExternal && (
+ <>
+
+ opens in new window
+ >
+ )}
+
+ )
+}
+```
+
+### Form Inputs
+
+```tsx
+type InputProps = {
+ label: string
+ error?: string
+ required?: boolean
+ 'aria-describedby'?: string
+ 'aria-invalid'?: boolean
+ 'aria-errormessage'?: string
+}
+
+export const Input = ({
+ label,
+ error,
+ required,
+ 'aria-describedby': ariaDescribedBy,
+ 'aria-invalid': ariaInvalid,
+ 'aria-errormessage': ariaErrorMessage,
+}: InputProps) => {
+ const inputId = useId()
+ const errorId = useId()
+
+ return (
+
+
+ {label}
+ {required && * }
+
+
+ {error && (
+
+ {error}
+
+ )}
+
+ )
+}
+```
+
+### Modals/Dialogs
+
+```tsx
+type ModalProps = {
+ isOpen: boolean
+ onClose: () => void
+ title: string
+ children: ReactNode
+}
+
+export const Modal = ({ isOpen, onClose, title, children }: ModalProps) => {
+ const titleId = useId()
+ const descriptionId = useId()
+
+ useEffect(() => {
+ if (isOpen) {
+ // Trap focus within modal
+ const focusableElements = modalRef.current?.querySelectorAll(
+ 'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
+ )
+ const firstElement = focusableElements?.[0]
+ const lastElement = focusableElements?.[focusableElements.length - 1]
+
+ const handleTabKey = (e: KeyboardEvent) => {
+ if (e.key === 'Tab') {
+ if (e.shiftKey && document.activeElement === firstElement) {
+ e.preventDefault()
+ lastElement?.focus()
+ } else if (!e.shiftKey && document.activeElement === lastElement) {
+ e.preventDefault()
+ firstElement?.focus()
+ }
+ }
+ if (e.key === 'Escape') {
+ onClose()
+ }
+ }
+
+ document.addEventListener('keydown', handleTabKey)
+ firstElement?.focus()
+
+ return () => document.removeEventListener('keydown', handleTabKey)
+ }
+ }, [isOpen, onClose])
+
+ if (!isOpen) return null
+
+ return (
+
+
{title}
+
+ {children}
+
+
+
+
+
+ )
+}
+```
+
+### Menus
+
+```tsx
+type MenuProps = {
+ isOpen: boolean
+ onClose: () => void
+ triggerRef: RefObject
+ children: ReactNode
+}
+
+export const Menu = ({ isOpen, onClose, triggerRef, children }: MenuProps) => {
+ const menuId = useId()
+ const menuRef = useRef(null)
+
+ useEffect(() => {
+ if (isOpen) {
+ menuRef.current?.querySelector('[role="menuitem"]')?.focus()
+
+ const handleKeyDown = (e: KeyboardEvent) => {
+ if (e.key === 'Escape') {
+ onClose()
+ triggerRef.current?.focus()
+ }
+ }
+
+ document.addEventListener('keydown', handleKeyDown)
+ return () => document.removeEventListener('keydown', handleKeyDown)
+ }
+ }, [isOpen, onClose, triggerRef])
+
+ if (!isOpen) return null
+
+ return (
+
+ )
+}
+
+type MenuItemProps = {
+ children: ReactNode
+ onClick: () => void
+ disabled?: boolean
+}
+
+export const MenuItem = ({ children, onClick, disabled }: MenuItemProps) => (
+ {
+ if (e.key === 'Enter' || e.key === ' ') {
+ e.preventDefault()
+ onClick()
+ }
+ }}
+ >
+ {children}
+
+)
+```
+
+## 🧪 Testing
+
+### Automated Testing with axe-core
+
+```tsx
+import { axe } from 'axe-core'
+import { expect } from 'vitest'
+import { render } from '@testing-library/react'
+
+it('should have no accessibility violations', async () => {
+ const { container } = render( )
+ const results = await axe(container)
+ expect(results).toHaveNoViolations()
+})
+
+// Test specific rules
+it('should have proper labels', async () => {
+ const { container } = render( )
+ const results = await axe(container, {
+ runOnly: {
+ type: 'rule',
+ values: ['label', 'button-name', 'link-name']
+ }
+ })
+ expect(results).toHaveNoViolations()
+})
+```
+
+### Manual Testing Checklist
+
+1. **Keyboard Navigation**
+ - Tab through all interactive elements
+ - Use Enter/Space to activate buttons
+ - Use Arrow keys for navigation within composite widgets
+ - Use Escape to close popups
+
+2. **Screen Reader Testing**
+ - Test with NVDA (Windows), JAWS (Windows), or VoiceOver (Mac)
+ - Verify all interactive elements are announced
+ - Verify state changes are announced
+ - Verify error messages are announced
+
+3. **Visual Testing**
+ - Zoom to 200% - verify content is still accessible
+ - Test in high contrast mode
+ - Verify focus indicators are visible
+ - Verify color is not the only means of conveying information
