3D Galaxy Animation with Pure HTML, CSS & JavaScript.
Dive into a lightweight 3D galaxy animation built with just HTML, CSS and vanilla JavaScript — no WebGL, Three.js, or external dependencies. This project demonstrates how layered transforms, CSS blend modes, gradients, and JavaScript-driven animation loops can combine to produce an immersive cosmic scene that performs well across modern browsers.
Features
Multi-layer starfield with configurable depth to create a realistic sense of distance.
Animated nebula/aurora layers using CSS gradients and mix-blend-mode for luminous effects.
Smooth camera-style movement implemented with requestAnimationFrame, easing, and decay for natural motion.
Mouse and device-orientation support so the scene reacts to pointer and phone tilt.
Responsive layout and retina-ready star rendering.
Minimal, well-commented codebase ideal for learning and customization.
Why this is useful
Learn how to create depth and motion without heavy frameworks.
Reuse as a hero background for portfolios, landing pages, or UI experiments.
Great stepping stone toward WebGL and Three.js — see how visuals can be achieved with simpler tools.
How it works
HTML: semantic layers and containers for stars and nebula elements.
CSS: transforms, animations, gradients, and blend modes to produce glow & color mixing.
JavaScript: generates stars, sets layer speeds, and runs an animation loop that adjusts transform properties based on pointer/device input.
Run locally
1. Clone or download the project.
2. Open index.html (or run a simple static server).
3. For best results, use Chrome/Firefox and test both desktop and mobile tilt.
Customize
Change star density, layer speeds, or nebula colors in the config block at the top of main.js.
Swap gradients to match your color theme.
Add floating particles, comet trails, or shader-based glow for advanced effects.
