What I built:
⚡ Sticky navbar with smooth scrolling and scroll-based active link highlighting
🎠 Auto-playing testimonials carousel that pauses on hover
🧩 Modal forms for Sign Up, Get Started and Contact Us, with keyboard support (Esc to close)
✨ Scroll-reveal animations using the Intersection Observer API
📱 A mobile-first responsive layout with a hamburger menu
♿ Accessibility basics: focus states, aria labels and reduced-motion support
