### 🎯 Core Features Implemented

</button>
```

- **Scroll Lock**: Prevents body scrolling when menu is open

## 🎨 Design Features

- Hover effects on navigation links
- Standard dropdown menus

### Mobile View (≤768px)

- Hamburger icon replaces navigation links
- Full-screen mobile menu overlay
- Animated hamburger-to-X icon transformation

## 🛠️ Technical Implementation

### CSS Architecture

```css
.hamburger-menu {
  display: none; /* Hidden on desktop */
  flex-direction: column;
  justify-content: space-around;
  /* Hamburger styling */
}

@media (max-width: 768px) {
  .hamburger-menu {
    display: flex; /* Show on mobile */
  }

  .nav-links {
    position: fixed;
    left: -100%; /* Hidden by default */
    /* Full-screen overlay styling */
  }

  .nav-links.active {
    left: 0; /* Slide in when active */
  }
}
```

### JavaScript Events

```javascript
// Toggle hamburger menu
hamburgerMenu.addEventListener("click", function () {
  hamburgerMenu.classList.toggle("active");
  navLinks.classList.toggle("active");

  // Prevent body scrolling
  document.body.style.overflow = navLinks.classList.contains("active")
    ? "hidden"
    : "";
});
```

## 📱 Mobile UX Enhancements

### Visual Effects

- **Slide Animation**: Menu slides in from left with smooth 0.3s transition

### Interaction Design

- **Touch Optimization**: 44px minimum touch targets
- **Auto-Close**: Tapping navigation links closes the menu
- **Dropdown Integration**: Mobile dropdowns expand vertically
