Single-Page Website Design with Fluid Interface

need a clean, fast, and responsive single-page website built in one file/page format. The website will be scroll-based with navigation links in a fixed header.

Sections required on the same page:

Header with Menu: Home, About, Service, Contact

Home Section – Professional intro content

About Section – Brief company overview

Service Section – Keep it as Demo placeholder for now (content services will be updated later)

Contact Section – A simple contact form (name, email, message, submit)

Contact Form Requirements:

Lightweight and functional UI

No backend needed right now, just frontend form

Should look professional and modern

Fields: Full Name, Email, Message + Submit Button

Design Expectations:

Minimal and premium feel

Mobile + Desktop responsive

Smooth scroll navigation

Placeholder content must be easy to update later

Fast loading and clean code

Tech Preference (optional for dev to choose):

HTML + Tailwind CSS (preferred) or any modern framework that fits single-page delivery.

Deliverables:

Fully working single-page website

Clean and well-structured code

Easy section updates for future content changes
