Navigation Menu UI Enhancement

I am ready to kick off a dedicated milestone that adds a brand-new user-interface feature: an upgraded navigation menu. The current menu does the job, but it feels dated and clunky on both desktop and mobile. I want the revised version to be visually polished, fully responsive, keyboard-accessible, and easy to extend as the site grows.

Here is what I’m looking for:

• Craft a modern, component-based navigation bar using clean HTML5, CSS3 (or a utility framework like Tailwind if you prefer), and lightweight JavaScript.
• Include smooth hover/focus states, dropdown or mega-menu support, and a collapsible mobile view driven by a hamburger toggle.
• Ensure WCAG-friendly keyboard navigation, ARIA labels, and logical tab order.
• Integrate the component into my existing codebase without breaking current routes—everything plugs into my backend exactly as it does today.
• Cross-browser testing (Chrome, Firefox, Safari, Edge) and device testing down to 320 px width.
• Provide concise setup notes plus a short Loom or GIF demo so I can see it working before merge.

Deliverables will be accepted when the updated menu is live on a staging branch, passes responsiveness and accessibility checks, and shows no console errors.

If you have questions about my current stack or need design assets, let me know and I’ll share them right away. Looking forward to seeing how you can level up the site’s first impression!
