+
+---
+
+## CSS Animations
+
+### 1. Keyframe Definitions
+
+#### `fadeIn` Animation
+**Purpose:** Fade element in from transparent to opaque
+**Duration:** 300ms | **Easing:** ease-out
+
+```css
+@keyframes fadeIn {
+ from {
+ opacity: 0;
+ }
+ to {
+ opacity: 1;
+ }
+}
+```
+
+**Usage:**
+- Page transitions
+- Component mount animations
+- Lazy-loaded element reveal
+
+**Example:**
+```html
+<div class="animate-fade-in">Content appears smoothly</div>
+```
+
+---
+
+#### `slideUp` Animation
+**Purpose:** Slide element up while fading in
+**Duration:** 300ms | **Easing:** ease-out
+**Distance:** 20px vertical movement
+
+```css
+@keyframes slideUp {
+ from {
+ opacity: 0;
+ transform: translateY(20px);
+ }
+ to {
+ opacity: 1;
+ transform: translateY(0);
+ }
+}
+```
+
+**Usage:**
+- Toast notifications
+- Card entrance effects
+- Content reveal on scroll
+
+**Example:**
+```html
+<div class="animate-slide-up">Card slides in from below</div>
+```
+
+---
+
+#### `modalSlideUp` Animation
+**Purpose:** Modal entrance animation (larger movement)
+**Duration:** 300ms | **Easing:** ease-out
+**Distance:** 30px vertical movement
+
+```css
+@keyframes modalSlideUp {
+ from {
+ opacity: 0;
+ transform: translateY(30px);
+ }
+ to {
+ opacity: 1;
+ transform: translateY(0);
+ }
+}
+```
+
+**Usage:**
+- Modal dialog opening
+- Important overlay content
+- Emphasis on critical user interaction
+
+**Example:**
+```html
+<div class="modal-content">Modal slides up into view</div>
+```
+
+Applied automatically via `.modal-content` class.
+
+---
+
+#### `spin` Animation
+**Purpose:** Continuous rotation for loading indicators
+**Duration:** 600ms | **Easing:** linear
+**Rotation:** 360 degrees full circle
+
+```css
+@keyframes spin {
+ from {
+ transform: rotate(0deg);
+ }
+ to {
+ transform: rotate(360deg);
+ }
+}
+```
+
+**Usage:**
+- Loading spinners
+- Progress indicators
+- Async operation feedback
+
+**Example:**
+```html
+<div class="spinner"></div>
+<div class="spinner-lg"></div>
+```
+
+Applied automatically to `.spinner` elements.
+
+---
+
+### 2. Animation Utility Classes
+
+#### `.animate-fade-in`
+Applies fadeIn keyframe animation (300ms)
+
+```css
+.animate-fade-in {
+ animation: fadeIn 300ms ease-out;
+}
+```
+
+**Use Cases:**
+- Initial page load
+- Conditional renders
+- Lazy-loaded components
+
+**HTML:**
+```html
+<div class="animate-fade-in">
+ <p>This content fades in</p>
+</div>
+```
+
+**Alpine.js Example:**
+```html
+<div x-show="isVisible" class="animate-fade-in">
+ Fades in when visible
+</div>
+```
+
+---
+
+#### `.animate-slide-up`
+Applies slideUp keyframe animation (300ms)
+
+```css
+.animate-slide-up {
+ animation: slideUp 300ms ease-out;
+}
+```
+
+**Use Cases:**
+- Toast notifications
+- Card reveals
+- List item entrance
+
+**HTML:**
+```html
+<div class="animate-slide-up">
+ <article class="card">Content slides up</article>
+</div>
+```
+
+**Alpine.js with Delay:**
+```html
+<template x-for="(item, idx) in items">
+ <div class="animate-slide-up" :style="`animation-delay: ${idx * 50}ms`">
+ {{ item.title }}
+ </div>
+</template>
+```
+
+---
+
+#### `.animate-spin-loader`
+Applies spin keyframe animation (600ms, linear)
+
+```css
+.animate-spin-loader {
+ animation: spin 600ms linear infinite;
+}
+```
+
+**Use Cases:**
+- Loading indicators
+- Async operation feedback
+- Data fetching states
+
+**HTML:**
+```html
+<button class="btn btn-primary" :disabled="isLoading">
+ <span class="spinner animate-spin-loader" x-show="isLoading"></span>
+ {{ isLoading ? 'Loading...' : 'Submit' }}
+</button>
+```
+
+---
+
+### 3. Animation Classes on Components
+
+#### Buttons - Hover/Active Transitions
+
+```css
+.btn:hover:not(:disabled) {
+ opacity: 0.85;
+ transform: translateY(-1px);
+ transition: all 200ms ease-out;
+}
+
+.btn:active:not(:disabled) {
+ transform: translateY(0);
+ opacity: 0.75;
+}
+```
+
+**Usage:** All buttons automatically respond to hover/active states with subtle lift effect (1px) and opacity change.
+
+---
+
+#### Form Input Focus Transitions
+
+```css
+.form-input:focus,
+.form-textarea:focus,
+.form-select:focus {
+ @apply ring-2 ring-accent ring-offset-2;
+ ring-offset-color: var(--bg);
+ transition: all 200ms ease-out;
+}
+```
+
+**Features:**
+- 2px ring in accent color
+- 2px offset from element
+- 200ms smooth transition
+- Respects prefers-reduced-motion
+
+---
+
+#### Modal Animations
+
+Modal content automatically uses `modalSlideUp` animation:
+
+```css
+.modal-content {
+ animation: modalSlideUp 0.3s ease-out;
+}
+```
+
+**Backdrop (fade):**
+```css
+.modal-backdrop {
+ animation: fadeIn 0.3s ease-out;
+}
+```
+
+---
+
+## Focus Management
+
+### Global `:focus-visible` Style
+
+All interactive elements have a visible focus indicator:
+
+```css
+*:focus-visible {
+ @apply ring-2 ring-accent ring-offset-2;
+ ring-offset-color: var(--bg);
+}
+```
+
+**Properties:**
+- **Ring:** 2px solid accent color
+- **Offset:** 2px from element
+- **Color:** Accent purple (dark) or dark purple (light theme)
+- **Contrast:** WCAG AAA compliant
+
+**Applies to:**
+- Buttons
+- Form inputs
+- Links
+- Modal close button
+- Select dropdowns
+- Any element with `tabindex`
+
+---
+
+### Input Focus States
+
+#### Focused Input
+```css
+.form-input:focus,
+.form-textarea:focus,
+.form-select:focus {
+ @apply ring-2 ring-accent ring-offset-2;
+ ring-offset-color: var(--bg);
+ transition: all 200ms ease-out;
+}
+```
+
+#### Invalid Input with Focus
+```css
+.form-input:invalid:focus,
+.form-textarea:invalid:focus,
+.form-select:invalid:focus {
+ ring-color: #ef4444; /* Red for errors */
+}
+```
+
+---
+
+### Checkbox and Radio Focus
+
+```css
+.form-checkbox:focus-visible,
+.form-radio:focus-visible {
+ @apply ring-2 ring-accent ring-offset-2;
+ ring-offset-color: var(--bg);
+}
+```
+
+---
+
+### Modal Focus Trap
+
+Modal implementation includes focus management via Alpine.js:
+
+```javascript
+// In Alpine component
+function modalData() {
+ return {
+ isOpen: false,
+ focusedElementBeforeOpen: null,
+
+ openModal() {
+ this.focusedElementBeforeOpen = document.activeElement;
+ this.isOpen = true;
+ // Focus first focusable element in modal
+ this.$nextTick(() => {
+ const firstFocusable = this.$refs.modal.querySelector('button, input, [tabindex]');
+ if (firstFocusable) firstFocusable.focus();
+ });
+ },
+
+ closeModal() {
+ this.isOpen = false;
+ // Restore focus to element that opened modal
+ if (this.focusedElementBeforeOpen) {
+ this.focusedElementBeforeOpen.focus();
+ }
+ },
+
+ handleKeydown(e) {
+ if (e.key === 'Escape') this.closeModal();
+ // Tab trap: keep focus within modal
+ if (e.key === 'Tab') {
+ const focusables = this.$refs.modal.querySelectorAll('button, input, [tabindex]');
+ const first = focusables[0];
+ const last = focusables[focusables.length - 1];
+
+ if (e.shiftKey && document.activeElement === first) {
+ e.preventDefault();
+ last.focus();
+ } else if (!e.shiftKey && document.activeElement === last) {
+ e.preventDefault();
+ first.focus();
+ }
+ }
+ }
+ }
+}
+```
+
+**Modal HTML Structure:**
+```html
+<div class="modal" :class="{ active: isOpen }" x-show="isOpen">
+ <div class="modal-backdrop" @click="closeModal()"></div>
+
+ <div class="modal-content"
+ x-ref="modal"
+ role="dialog"
+ aria-labelledby="modal-title"
+ @keydown="handleKeydown">
+
+ <div class="modal-header">
+ <h3 id="modal-title">Modal Title</h3>
+ <button aria-label="Close modal" @click="closeModal()">×</button>
+ </div>
+
+ <div class="modal-body">Content</div>
+ <div class="modal-footer">
+ <button @click="closeModal()">Cancel</button>
+ <button>Confirm</button>
+ </div>
+ </div>
+</div>
+```
+
+---
+
+## Keyboard Navigation
+
+### Tab Order and Navigation
+
+All interactive elements are keyboard accessible:
+
+| Element | Tab Key | Reverse Tab | Interaction |
+|---------|---------|-------------|-------------|
+| Button | Navigate | Navigate | Enter, Space |
+| Input | Navigate | Navigate | Type, Arrow keys (select) |
+| Link | Navigate | Navigate | Enter |
+| Checkbox | Navigate | Navigate | Space toggle |
+| Radio | Navigate | Navigate | Arrow keys select, Space toggle |
+| Select | Navigate | Navigate | Arrow keys, Space |
+| Modal | Tab trap | Tab trap | Escape closes |
+
+---
+
+### Keyboard Bindings Reference
+
+#### Global Keys
+- **Tab** — Move to next focusable element
+- **Shift+Tab** — Move to previous focusable element
+- **Enter** — Activate button, submit form
+- **Space** — Toggle checkbox/radio, activate button
+- **Escape** — Close modal, close dropdown
+
+#### Form Elements
+- **Input/Textarea** — Type to enter text
+- **Select** — Arrow Up/Down to change option
+- **Checkbox/Radio** — Space to toggle
+- **Form validation** — HTML5 `:invalid` pseudo-class
+
+#### Modal Focus Trap
+```javascript
+// When Tab pressed on last focusable element in modal:
+// → Focus cycles back to first focusable element
+// When Shift+Tab pressed on first focusable element:
+// → Focus cycles back to last focusable element
+// When Escape pressed:
+// → Modal closes, focus returns to opener
+```
+
+---
+
+### No Keyboard Traps
+
+All components ensure users can navigate away using keyboard:
+
+- ✅ Hamburger menu: Escape closes menu
+- ✅ Modal dialogs: Escape closes, Tab cycles (but doesn't escape)
+- ✅ Dropdowns: Can Tab past closed dropdown
+- ✅ Form fields: Tab navigates through all fields
+- ✅ No hidden traps: All focusable elements reachable via Tab
+
+**Validation:** Tab through entire page — should be able to reach all content and navigate away from any component.

+
+## Screen Reader Integration
+
+### Semantic HTML Foundation
+
+```html
+<!-- Proper label association -->
+<label for="email-input">Email Address</label>
+<input id="email-input" type="email">
+
+<!-- Form grouping -->
+<fieldset>
+ <legend>Select one option:</legend>
+ <label>
+ <input type="radio" name="option"> Option A
+ </label>
+ <label>
+ <input type="radio" name="option"> Option B
+ </label>
+</fieldset>
+
+<!-- Modal with ARIA labels -->
+<div role="dialog" aria-labelledby="title" aria-describedby="desc">
+ <h2 id="title">Confirm Action</h2>
+ <p id="desc">Are you sure?</p>
+</div>
+```
+
+---
+
+### ARIA Attributes
+
+#### Modal Dialogs
+```html
+<div role="dialog"
+ aria-labelledby="modal-title"
+ aria-modal="true"
+ aria-describedby="modal-description">
+ <h2 id="modal-title">Modal Title</h2>
+ <p id="modal-description">Modal description</p>
+</div>
+```
+
+**Attributes:**
+- `role="dialog"` — Identifies as modal dialog
+- `aria-labelledby="modal-title"` — Links to title element
+- `aria-describedby="modal-description"` — Links to description
+- `aria-modal="true"` — Indicates modal behavior
+
+#### Form Fields
+```html
+<div class="form-group">
+ <label for="input-name">Full Name</label>
+ <input id="input-name" type="text" aria-describedby="name-help">
+ <small id="name-help">Enter your full name (first and last)</small>
+</div>
+
+<!-- Error handling -->
+<input id="email" type="email" aria-invalid="true" aria-describedby="email-error">
+<span id="email-error">Invalid email address</span>
+```
+
+#### Buttons
+```html
+<!-- Icon button with accessible label -->
+<button aria-label="Close dialog">×</button>
+
+<!-- Loading state -->
+<button :aria-busy="isLoading" :disabled="isLoading">
+ <span class="spinner" x-show="isLoading" aria-hidden="true"></span>
+ {{ isLoading ? 'Saving...' : 'Save' }}
+</button>
+```
+
+#### Toast Notifications
+```html
+<div role="status" aria-live="polite" aria-atomic="true">
+ <span aria-hidden="true">✓</span>
+ <span>Settings saved successfully</span>
+</div>
+```
+
+**Attributes:**
+- `role="status"` — Announces status updates
+- `aria-live="polite"` — Announces changes without interrupting
+- `aria-atomic="true"` — Announces entire message
+- `aria-hidden="true"` — Hides decorative icons from readers
+
+---
+
+### Form Label Association
+
+All form inputs must have associated labels:
+
+```html
+<!-- Correct: explicit label association -->
+<label for="username">Username</label>
+<input id="username" type="text">
+
+<!-- Also correct: label wraps input -->
+<label>
+ Remember me
+ <input type="checkbox">
+</label>
+
+<!-- Incorrect: no label (avoid) -->
+<input type="text" placeholder="Username">
+```
+
+**Validation:**
+- Every `input` has an associated `label`
+- Labels use `for="id"` attribute
+- Input `id` matches label's `for` value
+- No orphaned inputs
+
+---
+
+### Semantic HTML Elements
+
+Use semantic tags for better screen reader navigation:
+
+```html
+<!-- Navigation -->
+<nav aria-label="Main navigation">
+ <a href="#home" tabindex="-1">Logo</a>
+ <button class="menu-toggle" aria-label="Toggle menu">Menu</button>
+</nav>
+
+<!-- Articles -->
+<article>
+ <h1>Article Title</h1>
+ <p>Article content</p>
+</article>
+
+<!-- Grouping -->
+<section>
+ <h2>Section Title</h2>
+</section>
+
+<!-- Lists -->
+<ul>
+ <li>Item 1</li>
+ <li>Item 2</li>
+</ul>
+```
+
+---
+
+## Motion Safety (prefers-reduced-motion)
+
+### Respecting User Preferences
+
+Users can prefer reduced motion in OS settings (Windows > Ease of Access, macOS > Accessibility, etc.). The theme respects this:
+
+```css
+/* Default: animations enabled */
+.btn:hover:not(:disabled) {
+ opacity: 0.85;
+ transform: translateY(-1px);
+ transition: all 200ms ease-out;
+}
+
+/* Motion-safe: disable animations if user prefers reduced motion */
+@media (prefers-reduced-motion: reduce) {
+ * {
+ animation-duration: 0.01ms !important;
+ animation-iteration-count: 1 !important;
+ transition-duration: 0.01ms !important;
+ }
+
+ .btn:hover:not(:disabled) {
+ transform: none;
+ opacity: 0.85;
+ }
+}
+```
+
+---
+
+### Animation Disabling
+
+When `prefers-reduced-motion: reduce` is active:
+
+1. **Animations:** Disabled (duration set to 0.01ms)
+2. **Transitions:** Disabled (duration set to 0.01ms)
+3. **Transforms:** Removed (no translateY, rotate, etc.)
+4. **Functionality:** Maintained (all features still work)
+
+**Example:**
+```css
+/* Default animation */
+.card {
+ animation: slideUp 300ms ease-out;
+}
+
+/* Motion-safe variant */
+@media (prefers-reduced-motion: reduce) {
+ .card {
+ animation-duration: 0.01ms;
+ }
+}
+```
+
+---
+
+### Testing Motion Preferences
+
+**macOS:**
+1. System Preferences > Accessibility > Display
+2. Enable "Reduce motion"
+3. Reload browser
+
+**Windows:**
+1. Settings > Ease of Access > Display
+2. Toggle "Show animations"
+
+**Linux (Firefox DevTools):**
+1. DevTools > Responsive Design Mode
+2. Touch/click settings icon
+3. Enable "prefers-reduced-motion: reduce"
+
+---
+
+## Performance Optimizations
+
+### GPU Acceleration
+
+Animations use GPU-accelerated properties:
+
+```css
+/* Good: GPU accelerated */
+transform: translateY(-1px);
+transform: rotate(360deg);
+opacity: 0.85;
+
+/* Bad: CPU intensive (avoid) */
+top: -1px;
+left: 0;
+height: 100px;
+```
+
+**Animatable Properties:**
+- `transform` ✅ (GPU)
+- `opacity` ✅ (GPU)
+- `visibility` ✅ (fast)
+- `background-color` ⚠️ (CPU, but acceptable)
+
+---
+
+### Animation Timing
+
+All animations follow consistent timing:
+
+| Component | Duration | Easing | Notes |
+|-----------|----------|--------|-------|
+| Button hover | 200ms | ease-out | Instant feedback |
+| Form focus | 200ms | ease-out | Input ring animation |
+| Modal open | 300ms | ease-out | Dialog entrance |
+| Toast appear | 300ms | ease-out | Notification entrance |
+| Spinner | 600ms | linear | Continuous rotation |
+
+---
+
+### CSS Build Performance
+
+**Week 5 CSS Stats:**
+- Total CSS lines: ~1,200 (human-readable)
+- Minified size: ~20KB
+- Build time: <250ms (Tailwind)
+- No runtime animation calculations
+
+**Optimization Techniques:**
+1. CSS `@keyframes` (no JS calculations)
+2. Hardware acceleration via `transform` and `opacity`
+3. Single animation rule per element (no stacking)
+4. Motion preferences checked at build time
+5. No heavy selectors in animations
+
+---
+
+## Code Examples & Usage
+
+### Basic Animation Usage
+
+#### Fade In Element
+```html
+<!-- Fades in when page loads -->
+<div class="animate-fade-in">
+ <h1>Welcome</h1>
+ <p>This content fades in smoothly</p>
+</div>
+```
+
+#### Slide Up Card
+```html
+<div class="card animate-slide-up">
+ <img src="image.jpg" alt="Preview">
+ <h3>Card Title</h3>
+ <p>Card description</p>
+ <a href="#">Read more →</a>
+</div>
+```
+
+#### Loading Spinner
+```html
+<button class="btn btn-primary" :disabled="isLoading">
+ <span class="spinner" x-show="isLoading"></span>
+ {{ isLoading ? 'Saving...' : 'Save Changes' }}
+</button>
+```
+
+---
+
+### Alpine.js Animation Patterns
+
+#### Conditional Fade In
+```html
+<div x-data="{ isVisible: false }">
+ <button @click="isVisible = !isVisible">Toggle</button>
+
+ <!-- Fades in when isVisible becomes true -->
+ <div x-show="isVisible" class="animate-fade-in">
+ Content appears with fade animation
+ </div>
+</div>
+```
+
+#### List Item Animation with Delay
+```html
+<div x-data="{ items: ['Item 1', 'Item 2', 'Item 3'] }">
+ <template x-for="(item, idx) in items">
+ <!-- Each item slides up with staggered delay -->
+ <div class="animate-slide-up" :style="`animation-delay: ${idx * 100}ms`">
+ {{ item }}
+ </div>
+ </template>
+</div>
+```
+
+#### Modal with Focus Management
+```html
+<div x-data="{ isOpen: false, focusedElement: null }">
+ <button @click="isOpen = true; focusedElement = $el">Open Modal</button>
+
+ <div class="modal" :class="{ active: isOpen }" x-show="isOpen">
+ <div class="modal-backdrop" @click="isOpen = false"></div>
+
+ <div class="modal-content animate-slide-up"
+ role="dialog"
+ aria-labelledby="title"
+ @keydown.escape="isOpen = false">
+
+ <div class="modal-header">
+ <h3 id="title">Modal Title</h3>
+ <button @click="isOpen = false" aria-label="Close">×</button>
+ </div>
+
+ <div class="modal-body">
+ <p>Modal content</p>
+ </div>
+
+ <div class="modal-footer">
+ <button @click="isOpen = false">Cancel</button>
+ <button>Confirm</button>
+ </div>
+ </div>
+ </div>
+</div>
+```
+
+#### Toast Notification
+```html
+<div x-data="{ toasts: [] }">
+ <button @click="toasts.push({ id: Date.now(), message: 'Success!' })">
+ Show Toast
+ </button>
+
+ <div class="toast-container">
+ <template x-for="toast in toasts">
+ <div class="toast toast-success animate-slide-up" :key="toast.id">
+ {{ toast.message }}
+ <button @click="toasts = toasts.filter(t => t.id !== toast.id)">×</button>
+ </div>
+ </template>
+ </div>
+</div>
+```
+
+---
+
+### Hover Effects
+
+#### Button Hover with Transform
+```css
+.btn:hover:not(:disabled) {
+ opacity: 0.85;
+ transform: translateY(-1px);
+ transition: all 200ms ease-out;
+}
+```
+
+**Visual Effect:** Button lifts 1px up on hover, slightly fades
+
+#### Link Hover
+```css
+a {
+ @apply text-accent hover:opacity-80 transition-opacity;
+}
+```
+
+**Visual Effect:** Link text slightly fades on hover
+
+#### Card Hover
+```css
+.card:hover {
+ box-shadow: 0 10px 30px rgba(168, 85, 247, 0.15);
+ transition: box-shadow 200ms ease-out;
+}
+```
+
+**Visual Effect:** Shadow increases on hover (depth effect)

+### WCAG 2.1 Standards
+
+- **WCAG 2.1 Level AA** — Target for this project
+- **Success Criterion 2.1.1** — Keyboard accessible
+- **Success Criterion 2.1.2** — No keyboard trap
+- **Success Criterion 2.4.7** — Focus visible
+- **Success Criterion 4.1.2** — Name, role, value
+- **Success Criterion 2.3.3** — Animation from interactions (prefers-reduced-motion)
+
+### Common Debugging Patterns
+
+#### Focus Ring Not Visible
+**Problem:** Users can't see which element has focus
+**Solution:**
+```css
+:focus-visible {
+ outline: 2px solid #a855f7;
+ outline-offset: 2px;
+}
+```
+
+#### Modal Not Trapping Focus
+**Problem:** Tab navigates outside modal
+**Solution:**
+```javascript
+// In modal keydown handler
+if (e.key === 'Tab') {
+ const focusables = modal.querySelectorAll('button, input, [tabindex]');
+ const first = focusables[0];
+ const last = focusables[focusables.length - 1];
+
+ if (e.shiftKey && document.activeElement === first) {
+ e.preventDefault();
+ last.focus();
+ } else if (!e.shiftKey && document.activeElement === last) {
+ e.preventDefault();
+ first.focus();
+ }
+}
+```
+
+#### Animations Jittery
+**Problem:** Animations stutter or skip frames
+**Solution:** Use GPU-accelerated properties only
+```css
+/* Good */
+.card { transform: translateY(10px); }
+
+/* Bad */
+.card { top: 10px; }
+```
+
+#### Motion Preferences Not Working
+**Problem:** Animations still play even with prefers-reduced-motion
+**Solution:**
+```css
+@media (prefers-reduced-motion: reduce) {
+ * {
+ animation-duration: 0.01ms !important;
+ transition-duration: 0.01ms !important;
+ }
+}
+```

+## Integration Notes
+
+### Using Animations in Your Pages
+
+**Simple fade-in for page load:**
+```html
+{{ define "baseof" }}
+<html>
+ <body class="animate-fade-in">
+ {{ block "main" . }}{{ end }}
+ </body>
+</html>
+{{ end }}
+```
+
+**Staggered card animations:**
+```html
+{{ define "cards" }}
+<div class="grid gap-6">
+ {{ range $idx, $item := .Items }}
+ <div class="card animate-slide-up" style="animation-delay: {{ mul $idx 50 }}ms">
+ {{ $item.Title }}
+ </div>
+ {{ end }}
+</div>
+{{ end }}
+```
+
+**Modal with full accessibility:**
+```html
+<div x-data="{ isOpen: false }" class="modal-dialog">
+ <button @click="isOpen = true">Open Modal</button>
+
+ <div class="modal" :class="{ active: isOpen }" x-show="isOpen">
+ <div class="modal-backdrop" @click="isOpen = false"></div>
+ <div class="modal-content"
+ role="dialog"
+ aria-labelledby="title">
+ <h2 id="title">Modal Title</h2>
+ <p>Modal content with full focus management and keyboard support</p>
+ </div>
+ </div>
+</div>
+```
