I need a sleek, single-page real-estate site built entirely with clean HTML5, CSS3 and vanilla JavaScript. The user journey should feel like a guided tour: as visitors scroll, sections glide in smoothly with tasteful, GPU-friendly animations. For micro-interactions, every primary call-to-action button and each property image should react on hover—subtle lifts, fades or zooms that feel fast and snappy without hindering performance. Code must be modular, well commented and easy for me to tweak later. Please keep load times low, minimise repaint/reflow, and make sure the page remains fully responsive across modern desktop and mobile browsers. Deliverables • Fully responsive single HTML file plus organised CSS & JS assets • Reusable property-card and CTA components with clearly labelled classes • Lightweight scrolling-animation logic (no large libraries) • A short README explaining where to adjust colours, copy and animation timing Acceptance criteria: smooth scroll animations without jank, hover effects trigger within 100 ms, zero console errors in the latest Chrome, Safari and Edge, and a Lighthouse performance score of 90+.
