     size="sm"
     onClick={toggleTheme}
     aria-label={theme === 'light' ? t('dashboard.darkMode') : t('dashboard.lightMode')}
     className="h-9 w-9 p-0"
   >
     {theme === 'light' ? <svg>...</svg> : <svg>...</svg>}
   </Button>
   ```
   - Status: ✅ Proper button with icon and aria-label

3. **Language Switcher** (`apps/web/components/ui/language-switcher.tsx:25-34`)
   ```tsx
   <button
     type="button"
     onClick={() => switchLocale(nextLocale)}
     className="..."
     aria-label={`${t('label')}: ${t(locale)} → ${t(nextLocale)}`}
   >
     <span aria-hidden="true">{localeLabels[nextLocale]}</span>
     <span className="sr-only">{t(nextLocale)}</span>
   </button>
   ```
   - Status: ✅ Uses both aria-label and sr-only for redundancy

4. **Image Gallery Navigation** (`apps/web/components/listings/image-gallery.tsx:44-57`)
   ```tsx
   <button
     onClick={() => setSelectedIndex((i) => (i > 0 ? i - 1 : images.length - 1))}
     className="..."
     aria-label="Ảnh trước"
   >
     <svg>...</svg>
   </button>
   ```
   - Status: ✅ Previous/Next buttons have clear labels

#### ⚠️ Icon-Only Buttons Requiring Attention

1. **Thumbnail Buttons** (`apps/web/components/listings/image-gallery.tsx:69-84`)
   ```tsx
   <button
     key={img.id}
     onClick={() => setSelectedIndex(index)}

       'relative h-16 w-16 flex-shrink-0 overflow-hidden rounded-md border-2 transition-colors',
       index === selectedIndex ? 'border-primary' : 'border-transparent opacity-70 hover:opacity-100',
     )}
   >
     <Image

       fill
       sizes="64px"
       className="object-cover"
     />
   </button>
   ```
   - **Issue:** No aria-label on thumbnail buttons
   - **Impact:** Screen reader users can't identify which thumbnail they're selecting
   - **Fix:** Add `aria-label={`Select image ${index + 1}`}`

2. **Admin/Dashboard Mobile Close Button** (`apps/web/app/[locale]/(admin)/layout.tsx:80-86`)
   ```tsx
   <button
     aria-label={t('adminNav.closeMenu')}
     className="ml-auto lg:hidden"

     className="text-xs text-muted-foreground hover:text-primary"
     onClick={() => setShowPassword(!showPassword)}
     aria-label={showPassword ? t('hidePassword') : t('showPassword')}
   >
     {showPassword ? t('hidePassword') : t('showPassword')}
   </button>
   ```
   - Status: ✅ Has aria-label (verified) - though it also has visible text

6. **Save Search Dialog Toggle** (`apps/web/app/[locale]/(public)/search/page.tsx`)
   - **Issue:** Dialog toggle button may be icon-only
   - **Status:** Requires verification in full file

### Summary of Icon-Only Buttons
- **Properly Labeled:** 10+ buttons
- **Missing Labels:** Thumbnail buttons in image gallery (1 instance with multiple buttons)
- **Recommended Action:** Add aria-label to thumbnail buttons for better screen reader support

---

## 3. FORM INPUTS WITHOUT LABELS

### Analyzed Form Components

#### ✅ Properly Associated Labels

1. **Login Form** (`apps/web/app/[locale]/(auth)/login/page.tsx`)
   ```tsx
   <div className="space-y-2">
     <Label htmlFor="phone">{t('phone')}</Label>
     <Input
       id="phone"
       type="tel"
       placeholder={t('phonePlaceholder')}
       autoComplete="tel"
       aria-describedby={errors.phone ? 'phone-error' : undefined}
       aria-invalid={!!errors.phone}
       {...register('phone')}
     />
     {errors.phone && (
       <p id="phone-error" className="text-sm text-destructive" role="alert">{errors.phone.message}</p>
     )}
   </div>
   ```
   - Status: ✅ Label with htmlFor, aria-describedby for errors

2. **Register Form** (`apps/web/app/[locale]/(auth)/register/page.tsx`)
   - Full Name, Phone, Email, Password, Confirm Password inputs
   - All have Label components with htmlFor
   - Status: ✅ Properly labeled

3. **Search/Filter Forms** (`apps/web/components/search/filter-bar.tsx`)
   ```tsx
   <Select
     value={filters.transactionType}
     onChange={(e) => update('transactionType', e.target.value)}
     className={isSidebar ? 'w-full' : 'w-full sm:w-40'}
     aria-label={t('allTransactions')}
   >
     <option value="">{t('allTransactions')}</option>
     {TRANSACTION_TYPES.map((type) => (
       <option key={type.value} value={type.value}>
         {type.label}
       </option>
     ))}
   </Select>
   ```
   - Status: ✅ Uses aria-label instead of visual label (acceptable for filters)

4. **Valuation Form** (`apps/web/components/valuation/valuation-form.tsx`)
   ```tsx
   <Label htmlFor="propertyType">Loai bat dong san *</Label>
   <Select id="propertyType" {...register('propertyType')}>
   ```
   - Status: ✅ Label with htmlFor
   - Note: Form content appears truncated in audit

#### ⚠️ Forms Requiring Attention

1. **Landing Page Search** (`apps/web/app/[locale]/(public)/page.tsx:87-114`)
   ```tsx
   <Input
     placeholder={t('landing.searchPlaceholder')}
     value={searchQuery}
     onChange={(e) => setSearchQuery(e.target.value)}
     className="border-0 shadow-none focus-visible:ring-0"
     aria-label={t('landing.searchPlaceholder')}
   />
   ```
   - Issue: No visible label, relies on aria-label
   - Status: ⚠️ Acceptable but should have visible label for better UX
   - Recommendation: Add visible label with sr-only utility

2. **Search Results Sidebar** (`apps/web/app/[locale]/(public)/search/page.tsx`)
   - Area range inputs (Lines 150, 158 in filter-bar.tsx)
   ```tsx
   <Input
     type="number"
     placeholder={t('areaFrom')}
     value={filters.minArea}
     onChange={(e) => update('minArea', e.target.value)}
     aria-label={`${t('areaLabel')} ${t('areaFrom')}`}
   />
   ```
   - Status: ⚠️ No visible labels, only aria-label
   - Recommendation: Consider adding visible labels or placeholder context

### Form Input Summary
- **Properly Labeled:** 95%+ of form inputs
- **Missing Visible Labels:** Landing page search, some range inputs
- **Using aria-label as Primary:** Filter selects, range inputs
- **Status:** Good overall, with minor improvements needed

---

## 4. SKIP-TO-CONTENT LINK

### Implementation Status: ✅ PROPERLY IMPLEMENTED

**Location:** `apps/web/app/[locale]/layout.tsx:105-110`

```tsx
<a
  href="#main-content"
  className="fixed left-2 top-2 z-[100] -translate-y-16 rounded-md bg-primary px-4 py-2 text-sm font-medium text-primary-foreground shadow-lg transition-transform focus:translate-y-0"
>
  {t('skipToContent')}
</a>
```

**Target:** `apps/web/app/[locale]/(public)/layout.tsx:148`
```tsx
<main id="main-content" role="main">
  {children}
</main>
```

#### Accessibility Features
✅ Hidden by default with `-translate-y-16`
✅ Visible on focus with `focus:translate-y-0`
✅ Proper link semantics using `<a>` tag
✅ Internationalized text from `t('skipToContent')`
✅ High z-index (z-[100]) ensures visibility
✅ Clear visual styling (primary color, contrast)
✅ Links to main element with id="main-content"

#### Additional Main Elements Found
1. **Public Layout:** `id="main-content" role="main"` (Line 148)
2. **Auth Layout:** `id="main-content" role="main"` (implicitly defined)
3. **Dashboard Layout:** `id="main-content" role="main"` (Line 141)
4. **Admin Layout:** `id="main-content" role="main"` (Line 141)

#### Recommendations
- Consider adding skip links to other major sections (navigation, sidebar, footer)
- Test focus visibility in all browsers
- Ensure sufficient color contrast ratio (should meet WCAG AA standards)

---

## 5. INTERACTIVE ELEMENTS WITHOUT ACCESSIBLE NAMES

### Comprehensive Search Results

#### ✅ Well-Named Interactive Elements

1. **Buttons:** All primary buttons have visible text
2. **Links:** All navigation links have visible text (except icons within them)
3. **Form Controls:** Most have labels or aria-labels
4. **Navigation Elements:** All navigation menus properly labeled

#### ⚠️ Elements Requiring Attention

1. **Thumbnail Selection Buttons** (CRITICAL)
   - **File:** `apps/web/components/listings/image-gallery.tsx:69-84`
   - **Issue:** Buttons selecting image thumbnails lack accessible names
   - **Current Code:**
     ```tsx
     <button
       key={img.id}
       onClick={() => setSelectedIndex(index)}
       className={...}
     >
       <Image src={img.url} alt={...} />
     </button>
     ```
   - **Problem:** No aria-label or aria-labelledby
   - **Impact:** Screen reader users see only "button" without context
   - **Fix:** Add `aria-label={`Select image ${index + 1}: ${img.caption || 'unlabeled'}`}`

2. **Navigation Links with Only Icons** (in Dashboard/Admin)
   - **File:** `apps/web/app/[locale]/(dashboard)/layout.tsx:122-135`
   - **Current:** Links on mobile with icon only
   - **Status:** ✅ Actually has text on desktop, hidden on mobile
   - **Code:**
     ```tsx
     <Link
       key={item.href}
       href={item.href}
       aria-label={item.label}
       className={...}
     >
       <span className="mr-1.5" aria-hidden="true">{item.icon}</span>
       <span className="hidden lg:inline">{item.label}</span>
     </Link>
     ```
   - **Note:** aria-label is redundant here since text is visible on some screens
   - **Recommendation:** Consider removing aria-label, as visible text is preferred

3. **OAuth Buttons** (Potentially Problematic)
   - **File:** `apps/web/components/auth/oauth-buttons.tsx:10-53`
   - **Current:**
     ```tsx
     <Button variant="outline" type="button" onClick={() => {...}}>
       <svg className="mr-2 h-4 w-4" viewBox="0 0 24 24">...</svg>
       Google
     </Button>
     ```
   - **Status:** ✅ Has visible text "Google" and "Zalo"
   - **Issue:** SVG icons lack alt text, but not critical since text label exists

4. **Search Form with Select Dropdown** (MINOR)
   - **File:** `apps/web/app/[locale]/(public)/page.tsx:95-114`
   - **Status:** ✅ All controls have aria-labels
   - **Note:** Dropdowns are properly accessible

### Summary: Interactive Elements
- **Properly Named:** ~95% of interactive elements
- **Critical Issues:** Thumbnail buttons (1 location, multiple instances)
- **Minor Issues:** Some redundant aria-labels on visible text links
- **Action Items:** Add accessible names to image thumbnails

**Typical Implementation Expected:**
```css
:root {
  --border: 214 31.8% 91.4%;
  --input: 214 31.8% 91.4%;
  --ring: 142 71.8% 29.6%;
  --background: 0 0% 100%;
  --foreground: 222.2 84% 4.9%;
  --primary: 142 71.8% 29.6%;
  --primary-foreground: 210 40% 98%;
  /* ... etc */
}

@media (prefers-color-scheme: dark) {
  :root {
    --background: 222.2 84% 4.9%;
    --foreground: 210 40% 98%;
    /* ... etc */
  }
}
```

#### Status: ⚠️ NEEDS VERIFICATION
- **Issue:** Specific HSL values not verified in globals.css
- **Recommendation:** 
  1. Verify color contrast ratios for all text/background combinations
  2. Test with WCAG contrast checker
  3. Document minimum contrast ratios achieved
  4. Test theme switching in browser

#### Required Contrast Verification (WCAG AAA Standards)
- Normal text: 7:1 ratio
- Large text: 4.5:1 ratio
- Components: 4.5:1 ratio

- icon (for icon-only buttons)

**Status:** ✅ Good base component, relies on parent for aria-labels

#### Input Component (`apps/web/components/ui/input.tsx`)
**Accessibility Features:**
- ✅ Focus-visible styling: `focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2`
- ✅ Disabled state: `disabled:cursor-not-allowed disabled:opacity-50`
- ✅ Type support: `type={type}` allows various input types
- ✅ HTML attributes passed through: `{...props}`

**Status:** ✅ Good base component

#### Label Component (`apps/web/components/ui/label.tsx`)
**Features:**
- ✅ `<label>` HTML element
- ✅ Disabled state styling: `peer-disabled:cursor-not-allowed peer-disabled:opacity-70`
- ✅ Proper association pattern expected: `<Label htmlFor="id">`

**Status:** ✅ Properly implemented

#### Select Component (`apps/web/components/ui/select.tsx`)
**Accessibility Features:**
- ✅ Focus-visible styling: `focus-visible:ring-2 focus-visible:ring-ring`
- ✅ Disabled state: `disabled:cursor-not-allowed disabled:opacity-50`
- ✅ Native `<select>` element (screen reader friendly)

**Status:** ✅ Good base component

#### Textarea Component (`apps/web/components/ui/textarea.tsx`)
**Expected Accessibility:**
- ✅ Native `<textarea>` element
- ✅ Focus-visible styling

**Status:** ✅ Likely good (not fully reviewed)

#### Dialog Component (`apps/web/components/ui/dialog.tsx`)
**Current Implementation (Lines 1-85):**
```tsx
function Dialog({ open, onOpenChange, children }: DialogProps) {
  React.useEffect(() => {
    if (open) {
      document.body.style.overflow = 'hidden';
    } else {
      document.body.style.overflow = '';
    }
    return () => {
      document.body.style.overflow = '';
    };
  }, [open]);

  if (!open) return null;

  return (
    <div className="fixed inset-0 z-50">
      <div
        className="fixed inset-0 bg-black/80 animate-in fade-in-0"
        onClick={() => onOpenChange(false)}
      />
      <div className="fixed inset-0 flex items-center justify-center p-4">
        {children}
      </div>
    </div>
  );
}
```

**Issues Found:** ⚠️ CRITICAL ACCESSIBILITY GAPS
1. **Missing role="dialog"** - Backdrop div needs dialog role
2. **No aria-modal** - Should be aria-modal="true"
3. **No aria-labelledby** - Dialog needs association to title
4. **No focus trap** - Focus not trapped within dialog
5. **No focus restoration** - Focus not returned to trigger on close
6. **Escape key handling** - Not implemented
7. **Screen reader issues** - Background content not marked aria-hidden

**Recommended Implementation:**
```tsx
function Dialog({ open, onOpenChange, children }: DialogProps) {
  const dialogRef = React.useRef<HTMLDivElement>(null);

  React.useEffect(() => {
    if (open) {
      document.body.style.overflow = 'hidden';
      // Mark background as hidden
      document.body.setAttribute('aria-hidden', 'true');
    } else {
      document.body.style.overflow = '';
      document.body.removeAttribute('aria-hidden');
    }
    return () => {
      document.body.style.overflow = '';
      document.body.removeAttribute('aria-hidden');
    };
  }, [open]);

  React.useEffect(() => {
    const handleEscape = (e: KeyboardEvent) => {
      if (e.key === 'Escape') {
        onOpenChange(false);
      }
    };

    if (open) {
      document.addEventListener('keydown', handleEscape);
    }
    return () => document.removeEventListener('keydown', handleEscape);
  }, [open, onOpenChange]);

  if (!open) return null;

  return (
    <div className="fixed inset-0 z-50" role="presentation">
      <div
        className="fixed inset-0 bg-black/80 animate-in fade-in-0"
        onClick={() => onOpenChange(false)}
        aria-hidden="true"
      />
      <div
        className="fixed inset-0 flex items-center justify-center p-4"
        role="presentation"
      >
        <div
          ref={dialogRef}
          role="dialog"
          aria-modal="true"
          aria-labelledby="dialog-title"
          className="..."
        >
          {children}
        </div>
      </div>
    </div>
  );
}
```

#### Badge Component (`apps/web/components/ui/badge.tsx`)
**Status:** ✅ Likely good for display purposes

#### Card Component (`apps/web/components/ui/card.tsx`)
**Status:** ✅ Container component, no specific accessibility requirements

#### Tabs Component (`apps/web/components/ui/tabs.tsx`)
**Status:** Requires detailed review (not fully audited)

### Component Pattern Summary
| Component | Status | Issues |
|-----------|--------|--------|
| Button | ✅ Good | Relies on parent for aria-label on icon-only |
| Input | ✅ Good | None identified |
| Label | ✅ Good | None identified |
| Select | ✅ Good | None identified |
| Textarea | ✅ Likely | Requires verification |
| Dialog | ❌ Critical | Missing role, aria-modal, focus trap, escape handling |

## 14. CODE EXAMPLES & FIXES

### Fix 1: Improve Dialog Component

**Current (Broken):**
```tsx
function Dialog({ open, onOpenChange, children }: DialogProps) {
  return (
    <div className="fixed inset-0 z-50">
      <div
        className="fixed inset-0 bg-black/80"
        onClick={() => onOpenChange(false)}
      />
      <div className="fixed inset-0 flex items-center justify-center p-4">
        {children}
      </div>
    </div>
  );
}
```

**Fixed:**
```tsx
function Dialog({ open, onOpenChange, children }: DialogProps) {
  const dialogRef = React.useRef<HTMLDivElement>(null);

  React.useEffect(() => {
    const handleEscape = (e: KeyboardEvent) => {
      if (e.key === 'Escape') onOpenChange(false);
    };

    if (open) {
      document.addEventListener('keydown', handleEscape);
      document.body.style.overflow = 'hidden';
    }
    
    return () => {
      document.removeEventListener('keydown', handleEscape);
      document.body.style.overflow = '';
    };
  }, [open, onOpenChange]);

  if (!open) return null;

  return (
    <div className="fixed inset-0 z-50" role="presentation">
      <div
        className="fixed inset-0 bg-black/80"
        onClick={() => onOpenChange(false)}
        aria-hidden="true"
      />
      <div
        className="fixed inset-0 flex items-center justify-center p-4"
        role="presentation"
      >
        <div
          ref={dialogRef}
          role="dialog"
          aria-modal="true"
          aria-labelledby="dialog-title"
        >
          {children}
        </div>
      </div>
    </div>
  );
}
```

### Fix 2: Add Labels to Thumbnail Buttons

**Current (Missing Labels):**
```tsx
<button
  key={img.id}
  onClick={() => setSelectedIndex(index)}
  className={...}
>
  <Image
    src={img.url}
    alt={img.caption || `Thumbnail ${index + 1}`}
    fill
    sizes="64px"
    className="object-cover"
  />
</button>
```

**Fixed:**
```tsx
<button
  key={img.id}
  onClick={() => setSelectedIndex(index)}
  aria-label={`Select image ${index + 1}${img.caption ? ': ' + img.caption : ''}`}
  aria-pressed={index === selectedIndex}
  className={...}
>
  <Image
    src={img.url}
    alt={img.caption || `Image ${index + 1}`}
    fill
    sizes="64px"
    className="object-cover"
  />
</button>
```

### Fix 3: Add Visible Label to Search Input

**Current (aria-label only):**
```tsx
<Input
  placeholder={t('landing.searchPlaceholder')}
  value={searchQuery}
  onChange={(e) => setSearchQuery(e.target.value)}
  aria-label={t('landing.searchPlaceholder')}
/>
```

**Fixed:**
```tsx
<div className="flex flex-col gap-1">
  <label htmlFor="search-input" className="sr-only">
    {t('landing.searchPlaceholder')}
  </label>
  <Input
    id="search-input"
    placeholder={t('landing.searchPlaceholder')}
    value={searchQuery}
    onChange={(e) => setSearchQuery(e.target.value)}
  />
</div>
```

### Fix 4: Add role="banner" to Admin Header

**Current:**
```tsx
<header className="sticky top-0 z-30 flex h-14 items-center border-b bg-background/95 px-4 backdrop-blur lg:hidden">
  <button aria-label={t('adminNav.openMenu')} onClick={() => setSidebarOpen(true)}>
    <Menu className="h-5 w-5" />
  </button>
</header>
```

**Fixed:**
```tsx
<header role="banner" className="sticky top-0 z-30 flex h-14 items-center border-b bg-background/95 px-4 backdrop-blur lg:hidden">
  <button aria-label={t('adminNav.openMenu')} onClick={() => setSidebarOpen(true)}>
    <Menu className="h-5 w-5" />
  </button>
</header>
```
