Modern 3D Animated Website

I'll create a modern single-page website with 3D animations using only HTML, CSS, and vanilla JavaScript. The design will include a fullscreen landing section with floating 3D elements, smooth scrolling, and responsive design.

Key Features of This 3D Animated Website

This modern single-page website includes all the requested features:

1. 3D Animated Background: The landing section features a fullscreen 3D background with randomly positioned and animated cubes created using CSS 3D transforms and JavaScript.
2. Smooth Scroll Animations: The website implements smooth scrolling between sections using JavaScript, and elements animate into view as you scroll down the page using Intersection Observer.
3. Sticky Navigation: The navigation bar changes style on scroll, becoming more prominent with a background and shadow when scrolling down.
4. Responsive Design: The layout adapts to different screen sizes with media queries, ensuring a good experience on both desktop and mobile devices.

5. Interactive Elements:

   • 3D rotating cubes in the hero section
   • 3D floating cube in the about section
   • 3D rotating icons in the services section
   • Interactive portfolio items with hover effects
   • Animated form inputs
6. Modern Typography and Layout: Clean, modern design with a cohesive color scheme and typography.
7. Performance Optimized: The animations are hardware-accelerated using CSS transforms and the code is structured for optimal performance.

All the code is self-contained in the three requested files (HTML, CSS, and JavaScript) with no external dependencies or libraries.
