CSS Scroll-Driven
& View Transition Patterns

Master native CSS scroll-timeline and the @view-transition API. Eliminate JavaScript overhead, hit 60fps frame budgets, and build inclusive motion that works for everyone — on any device.

Accessibility & Inclusive Motion Core Fundamentals Implementation Patterns

Modern web interfaces increasingly rely on declarative, GPU-accelerated motion to guide user attention without compromising performance or accessibility. By using native browser APIs — animation-timeline: scroll(), view(), and document.startViewTransition() — engineering teams can move complex animation logic off the main thread entirely, achieving deterministic frame timing that was once only possible with heavyweight JavaScript libraries.

This site is a technical reference for frontend developers, UX/UI engineers, and motion designers who need to implement, debug, and optimize CSS scroll-driven animations and page transitions in production applications. Every pattern includes compositor-safe CSS, progressive enhancement strategies, framework sync examples for React, Vue, and Svelte, and strict prefers-reduced-motion support.

Whether you're building a reading progress bar with pure CSS, wiring the View Transitions API into a React Router SPA, or debugging jank on a parallax layer — this reference covers the rendering pipeline mechanics you need to understand why each technique works, not just how to implement it.
