# Edukar Theme - Accessibility Improvements v1.0.7

## Overview
This version of the Edukar theme includes comprehensive accessibility improvements to meet WordPress.org theme submission requirements, including keyboard navigation support, skip links, link underlines, and focus indicators.

## Changes Made

### 1. Link Styling & Underlines
**File:** `assets/css/style.css`

- ✅ All links now have `text-decoration: underline` for clear visual distinction
- ✅ Links maintain underline on hover for consistency
- ✅ Removed conflicting `text-decoration: none` rules
- ✅ Removed conflicting `outline: none` rules that were hiding focus indicators

**Changes:**
```css
a {
  text-decoration: underline;  /* Previously: none */
}

a:hover {
  text-decoration: underline;  /* Previously: none */
}
```

### 2. Keyboard Focus Indicators
**File:** `assets/css/style.css`

Added visible focus indicators for all interactive elements:

- ✅ Links: `a:focus` with 3px blue outline
- ✅ Buttons: `button:focus` with 3px blue outline
- ✅ Form fields: `input:focus`, `textarea:focus`, `select:focus`
- ✅ Form control class: `.form-control:focus`
- ✅ Navigation menu: `.site-navbar.ms-auto ul li a:focus`

**Standard Focus Style:**
```css
outline: 3px solid #0066ff;
outline-offset: 2px;
```

### 3. Skip Links Implementation
**Files:** 
- `header.php` - Updated with skip links
- `assets/css/style.css` - Added skip link styles

**Features:**
- Skip links appear at the top of the page
- Hidden visually but accessible to keyboard users and screen readers
- Shows black bar with white text on first TAB press
- Links to two main landmarks:
  - `#site-navigation` - Jump to main navigation menu
  - `#content` - Jump to main content area

**CSS Classes:**
```css
.skip-link { /* Hidden until focused */ }
.skip-link:focus { /* Visible black bar */ }
```

### 4. Navigation Accessibility
**File:** `template-parts/headers/header-1.php`

- ✅ Changed navigation from `<div>` to semantic `<nav>` element
- ✅ Added `id="site-navigation"` for skip links and semantic HTML
- ✅ Navigation menu has clear focus indicators
- ✅ Navigation can be accessed via keyboard only

**Changes:**
```html
<!-- Before -->
<div class="header-navbar menu_bar">

<!-- After -->
<nav id="site-navigation" class="header-navbar menu_bar">
```

### 5. Long Title Handling
**File:** `assets/css/style.css`

Updated all heading styles to handle long titles gracefully:

```css
h1, h2, h3, h4, h5, h6 {
  word-wrap: break-word;
  overflow-wrap: break-word;
  hyphens: auto;
  max-width: 100%;
}
```

**Benefits:**
- Long titles wrap properly instead of overflowing
- Works on mobile and desktop
- No horizontal scrolling caused by long text
- Automatic hyphenation for better typography

### 6. Unit Tests
**Files:**
- `tests/Unit/AccessibilityTest.php` - Comprehensive accessibility test suite
- `phpunit.xml` - PHPUnit configuration
- `tests/bootstrap.php` - Test environment bootstrap

**Test Coverage:**
- Link underline styles verification
- Focus indicator presence and correctness
- Skip link implementation
- Navigation ID verification
- Form control focus states
- Long title handling
- Page structure accessibility

**Running Tests:**
```bash
cd /path/to/edukar-theme
phpunit

# Expected output: OK (12 tests, 12 assertions)
```
