Premium Demo
Showcasing advanced web techniques: scroll tracking, viewport detection, easing, LERP, shader effects, text splitting, and view transitions.
Advanced Techniques
Built with modern web APIs and optimized for performance
Scroll Tracking
Monitor user engagement with viewport detection, scroll depth tracking, and section visibility analytics. Know exactly what users see and interact with.
Smooth Animations
LERP-based animations create buttery-smooth interactions. From cursor following to parallax scrolling, every movement feels natural and polished.
Shader Effects
GPU-accelerated particle systems and gradient effects. Premium visual polish without heavy JavaScript libraries or performance hits.
Interactive Demos
Experience the techniques in action
Smooth Easing Curves
Hover over the cards above to see elastic easing in action. Click buttons to feel the snap effect. Everything uses custom cubic-bezier curves.
Value Mapping
Scroll position is mapped to opacity, scale, and color changes throughout the page. The reading progress bar uses MAP to convert scroll to percentage.
Try it: Watch the progress bar at the top as you scroll.
Linear Interpolation
The custom cursor smoothly follows your mouse using LERP. Counters animate using interpolated values. Particles respond to mouse movement with eased physics.
Try it: Move your mouse around to see the cursor lag smoothly.
Frequently Asked Questions
Common questions about these techniques
What browsers support these features?
All modern browsers support these techniques. View Transitions API is Chrome/Edge only, but gracefully degrades. Everything works on mobile Safari, Chrome, Firefox, and Edge.
Does this impact performance?
No! These techniques use requestAnimationFrame, GPU acceleration, and passive event listeners for 60fps performance. Particle count adjusts based on device capabilities.
Is this accessible?
Yes. All animations respect prefers-reduced-motion. Focus states are visible. Keyboard navigation works everywhere. ARIA labels and semantic HTML throughout.
Can I use this in production?
Absolutely! This code is production-ready. It's optimized, accessible, and includes fallbacks for older browsers. Perfect for SpeedMobi client sites.
