I need a complete front-end build that feels colorful and vibrant while still loading quickly and behaving consistently across every modern browser. You can work in plain HTML/CSS/JavaScript or jump straight into React with Tailwind CSS; whichever stack you choose, the final code must be clean, well-structured, and fully commented so I can extend it later. I already have a basic color scheme in mind but no formal brand book, so part of the task is proposing complementary typography, spacing, and accent hues that keep the interface lively without overwhelming the user. The site must adapt perfectly on mobile, tablet, and desktop. I will run responsive checks with native device tools and Chrome DevTools, so breakpoints and fluid layouts need to be rock-solid. Smooth, lightweight animations—think subtle fades and slide-ins—should enhance, not distract from, the experience. Key deliverables • Four pages: Home, Login/Signup, Product/List, and Contact • Search bar with real-time filtering on the Product/List page • Cross-browser compatibility (latest Chrome, Firefox, Safari, Edge) • Source code handed over via Git or ZIP, ready to npm install / live-serve • Up to two minor revision rounds after initial delivery Meeting these points in a tidy, well-commented codebase will be the acceptance criteria for project sign-off.
