I want to launch a sleek, modern-and-minimalist website where content comes alive as the visitor scrolls. Every key element—headlines, images, and call-to-action buttons—should reveal itself through smooth scroll-triggered animations that feel natural rather than gimmicky. No hover tricks or loading spinners are required; the focus is strictly on scroll-based motion. Here’s the flow I have in mind: • A clean hero section that fades or slides into view. • Subsequent sections that stagger content or parallax subtly as the user moves down the page. • Lightweight, performance-friendly techniques—think GSAP, ScrollTrigger, or native CSS / JavaScript—so the site remains fast on mobile. I’ll supply brand colours, copy, and any imagery once we kick off. What I need from you is a polished, responsive build (HTML/CSS/JS or your preferred modern framework) plus hand-off assets ready for deployment. When you reply, include a concise but detailed project proposal outlining your concept approach, animation toolkit, estimated timeline, and any relevant examples of past scroll-animation work.
