Accessibility ensures that everyone can interact with web content equally, and JavaScript is a powerful tool for creating accessible user interfaces. The following code demonstrates a simple, accessible menu design that serves as a foundation for building more complex and standards-compliant interfaces.

const toggle = document.querySelector('#toggleMenu');
const menu = document.querySelector('#menu');

toggle.addEventListener('click', () => {
    menu.hidden = !menu.hidden; // Toggle menu visibility
});

document.addEventListener('keydown', ({ key }) => {
    if (key === 'Escape' && !menu.hidden) menu.hidden = true; // Close menu with Escape
});

Why This Code Demonstrates Accessibility

• Escape Key Support: Users can close the menu using the Escape key, which is essential for keyboard navigation.
• hidden Attribute: The hidden attribute ensures that the menu is not accessible to screen readers when closed, but fully accessible when open.
• Keyboard Navigation: The menu can be operated without a mouse, making it suitable for users relying on keyboards.

How This Can Be Expanded

• More Complex Interfaces: Use this foundation to create tabs, modals, or accessible forms.
• ARIA Roles and Attributes: Add role="menu" or aria-expanded for enhanced accessibility.
• Responsive Design: Optimize for different devices and ensure usability across all screen sizes.

This JavaScript example highlights the basics of building an accessible menu. It is a small but impactful step towards creating user-friendly and inclusive interfaces. Use this as a starting point to craft more advanced, accessible designs!
