```
### Navigation Accessibility
#### Accessible Navigation Menu
```rust
#[component]
pub fn AccessibleNavigation() -> impl IntoView {
let (is_menu_open, set_is_menu_open) = signal(false);
let (active_item, set_active_item) = signal("home".to_string());
let menu_items = vec![
("home", "Home", "/"),

];
let toggle_menu = move |_| {
set_is_menu_open.update(|open| *open = !*open);
};
let select_item = move |item_id: String| {
set_active_item.set(item_id);
set_is_menu_open.set(false);
};
view! {
<nav role="navigation" aria_label="Main navigation">
<div class="flex items-center justify-between">
// Menu button
<ButtonNewYork
variant=ButtonVariantNewYork::Ghost
on_click=toggle_menu
aria_expanded=move || is_menu_open.get()

</div>
</nav>
}
}
```
## 🧪 Testing Strategies
### Automated Accessibility Testing
#### Playwright Accessibility Tests
```typescript
import { test, expect } from '@playwright/test';
test.describe('Accessibility Tests', () => {
test('button accessibility', async ({ page }) => {
await page.goto('/');
// Test keyboard navigation
await page.keyboard.press('Tab');
const focusedElement = page.locator(':focus');
await expect(focusedElement).toBeVisible();
// Test button activation
await page.keyboard.press('Enter');
// Verify button action occurred
// Test ARIA attributes
const button = page.locator('button').first();
await expect(button).toHaveAttribute('role', 'button');
await expect(button).toHaveAttribute('aria-label');
});
test('form accessibility', async ({ page }) => {
await page.goto('/');
// Test form structure
const form = page.locator('form');
await expect(form).toHaveAttribute('role', 'form');
// Test label associations
const inputs = page.locator('input');
for (let i = 0; i < await inputs.count(); i++) {
const input = inputs.nth(i);
const id = await input.getAttribute('id');
if (id) {
const label = page.locator(`label[for="${id}"]`);
await expect(label).toBeVisible();
}
}
// Test error handling
const submitButton = page.locator('button[type="submit"]');
await submitButton.click();
const errorMessages = page.locator('[role="alert"]');
await expect(errorMessages).toBeVisible();
});
test('modal accessibility', async ({ page }) => {
await page.goto('/');
// Open modal
const modalTrigger = page.locator('[aria-haspopup="dialog"]');
await modalTrigger.click();
// Test modal attributes
const modal = page.locator('[role="dialog"]');
await expect(modal).toHaveAttribute('aria-modal', 'true');
await expect(modal).toHaveAttribute('aria-labelledby');
await expect(modal).toHaveAttribute('aria-describedby');
// Test focus management
const focusedElement = page.locator(':focus');
await expect(focusedElement).toBeVisible();
// Test escape key
await page.keyboard.press('Escape');
await expect(modal).not.toBeVisible();
});
});
```
### Manual Testing Checklist
#### Keyboard Navigation
- [ ] All interactive elements are reachable via Tab key
- [ ] Tab order is logical and intuitive
- [ ] Focus indicators are clearly visible
- [ ] Enter and Space keys activate buttons
- [ ] Arrow keys navigate within groups
- [ ] Escape key closes modals and dropdowns
#### Screen Reader Testing
- [ ] All content is announced correctly
- [ ] Form labels are properly associated
- [ ] Error messages are announced
- [ ] Status changes are communicated
- [ ] Navigation landmarks are identified
- [ ] Button purposes are clear
#### Visual Testing
- [ ] Color contrast meets WCAG AA standards
- [ ] Text is readable at 200% zoom
- [ ] Focus indicators are visible
- [ ] Error states are clearly indicated
- [ ] Loading states are communicated
- [ ] Information is not conveyed by color alone
## ✅ Best Practices
### 1. Semantic HTML
```rust
// ✅ Good: Use semantic elements
<main role="main">
<section aria_labelledby="section-title">
<h2 id="section-title">"User Settings"</h2>
// Content
</section>
</main>
// ❌ Avoid: Generic divs without meaning
<div>
<div>
<div>"User Settings"</div>
// Content
</div>
</div>
```
### 2. ARIA Labels and Descriptions
```rust
// ✅ Good: Provide clear labels
<ButtonNewYork
aria_label="Save user profile and return to dashboard"
aria_describedby="save-button-help"
>
"Save"
</ButtonNewYork>
<div id="save-button-help" class="sr-only">
"This will save your changes and redirect you to the main page."
</div>
// ❌ Avoid: Vague or missing labels
<ButtonNewYork>"Save"</ButtonNewYork>
```
### 3. Focus Management
```rust
// ✅ Good: Manage focus properly
let (is_modal_open, set_is_modal_open) = signal(false);
Effect::new(move |_| {
if is_modal_open.get() {
// Focus first interactive element in modal
focus_first_interactive_element();
} else {
// Return focus to trigger element
focus_trigger_element();
}
});
// ❌ Avoid: Letting focus get lost
let (is_modal_open, set_is_modal_open) = signal(false);
// No focus management
```
### 4. Error Handling
```rust
// ✅ Good: Accessible error messages
{move || if let Some(error) = errors.get().name.clone() {
view! {
<div
role="alert"
aria_live="polite"
class="text-red-600"
>
{error}
</div>
}
} else {
view! { <div></div> }
}}
// ❌ Avoid: Visual-only error indicators
{move || if let Some(error) = errors.get().name.clone() {
view! {
<div class="text-red-600">
{error}
</div>
}
} else {
view! { <div></div> }
}}
```
### 5. Loading States
```rust
// ✅ Good: Communicate loading states
<ButtonNewYork
disabled=move || is_loading.get()
aria_label=move || if is_loading.get() { "Saving data, please wait" } else { "Save data" }
>
{move || if is_loading.get() { "Saving..." } else { "Save" }}
</ButtonNewYork>
// ❌ Avoid: Unclear loading states
<ButtonNewYork disabled=move || is_loading.get()>
{move || if is_loading.get() { "..." } else { "Save" }}
</ButtonNewYork>
```
## 🚨 Common Issues and Solutions
### Issue 1: Missing Focus Indicators
**Problem**: Users can't see which element has focus.
**Solution**:
```rust
// Add focus styles
<ButtonNewYork
class="focus:outline-none focus:ring-2 focus:ring-blue-500 focus:ring-offset-2"
>
"Button"
</ButtonNewYork>
```
### Issue 2: Unclear Button Purposes
**Problem**: Screen readers announce "Button" without context.
**Solution**:
```rust
<ButtonNewYork
aria_label="Delete user account permanently"
aria_describedby="delete-warning"
>
"Delete"
</ButtonNewYork>
<div id="delete-warning" class="sr-only">
"This action cannot be undone and will permanently remove your account."
</div>
```
### Issue 3: Form Validation Not Announced
**Problem**: Error messages aren't communicated to screen readers.
**Solution**:
```rust
{move || if let Some(error) = validation_error.get() {
view! {
<div
role="alert"
aria_live="polite"
class="text-red-600"
>
{error}
</div>
}
} else {
view! { <div></div> }
}}
```
### Issue 4: Modal Focus Management
**Problem**: Focus escapes modal and goes to background content.
**Solution**:
```rust
// Implement focus trap
let (modal_ref, set_modal_ref) = signal(None::<HtmlElement<html::Div>>);
Effect::new(move |_| {
if let Some(modal) = modal_ref.get() {
// Trap focus within modal
trap_focus(modal);
}
});
```
### Issue 5: Color-Only Information
**Problem**: Information is conveyed only through color.
**Solution**:
```rust
// Add text indicators alongside color
<div class="flex items-center space-x-2">
<div class="w-3 h-3 bg-green-500 rounded-full"></div>
<span class="text-green-600 font-medium">"Active"</span>
</div>
```
