I need a clean, modern, and fully responsive one-page landing page built with vanilla HTML, CSS, and JavaScript. The page will showcase a single product for general consumers, so every section must funnel visitors toward a clear purchase call-to-action. Core layout • Hero header with a bold CTA button • Feature section highlighting key benefits or specifications • Concise product overview paragraph with supporting visuals • Footer containing basic links and contact information Technical notes The markup should be semantic, CSS organised and commented, and any JavaScript limited to lightweight interactions such as smooth scrolling and a mobile menu—no heavy frameworks unless we agree otherwise. I’ll be testing on mobile, tablet, and desktop widths; the design must adapt flawlessly and load quickly (aiming for 90+ on Lighthouse performance and accessibility). Timeline & budget Turnaround is 3–5 days and the project sits in a beginner-friendly budget range, so an efficient, self-contained solution is ideal. Deliverables 1. index.html, styles.css, and script.js 2. Optimised images or icons with clear licensing 3. Brief read-me with setup instructions Acceptance criteria: responsive behaviour across major browsers, functioning CTAs, and fast load performance. If this fits your skill set, let’s get started.
