React Parallax
React Parallax is a React animation component library that creates multi-speed scrolling background depth effects. It computes relative scroll positions within viewports to translate raw page offsets into normalized animation progress values, applying hardware-accelerated translation and scaling styles to DOM nodes for smooth visual movement.
The library supports rendering background images and arbitrary visual elements that shift positions at different speeds relative to foreground content. It provides dynamic Gaussian blur filter transitions that interpolate based on current scroll velocity and position.
Child components and custom animations are driven through a render-props composition pattern, which exposes raw scroll percentage values for custom page transformations and dynamic visual customization.
