JazzHands is a UIKit framework providing a scroll-driven animation engine and a paging layout manager. It enables the binding of view properties to timelines of keyframes, allowing visual transitions to be synced with real-time scroll offsets or gesture data. The project distinguishes itself through a value-interpolation engine that calculates intermediate property states. This allows animation progress to be driven by external input values, mapping view attributes to a timeline based on a floating point progress indicator. The framework also includes a system for organizing views within pag

WebSlides is a CSS-class-driven presentation framework that turns HTML sections into full-screen slides with keyboard, touch, and remote navigation. Its core architecture defines slides as HTML section elements styled entirely through CSS classes for layout, animation, and background, with a vertical-rhythm spacing foundation using an 8-pixel baseline grid. The framework includes a plugin-based behavior extension system that hooks into slide lifecycle events, and maps each slide to a unique URL hash for direct permalink navigation. The framework distinguishes itself through a comprehensive se

Este proyecto proporciona wrappers de componentes y gestores que automatizan la sincronización entre la visibilidad del teclado de software y la posición de desplazamiento de los elementos de entrada activos. Es una vista de desplazamiento de teclado móvil multiplataforma diseñada para mantener las entradas de texto activas visibles sobre el teclado de software. La biblioteca funciona como un wrapper de componentes consciente del teclado que detecta eventos del teclado de software para evitar que los campos de entrada queden ocultos.

Incluye instrucciones sobre diseño de movimiento, que van desde animaciones activadas por desplazamiento y animación de hojas de sprites hasta la creación de animaciones complejas de interfaces web. El material cubre capacidades básicas como la manipulación de la geometría de elementos, el control del ritmo de animación y la gestión de estados de reproducción. También aborda áreas técnicas que incluyen interpolación de estados, renderizado 3D y la sincronización de múltiples animaciones. Los usuarios pueden recibir tutoriales semanales para aprender nuevas técnicas visuales y guías de animación.

This is a React animation library providing a collection of components for creating choreographed motion, complex transitions, and SVG morphing. It functions as a motion design specification and a UI component animation wrapper system used to apply 3D transforms, Bezier curves, and entry-exit transitions to interface elements. The project includes a scroll-driven animation suite for synchronizing UI movements and parallax effects with the viewport position, as well as an SVG motion framework for animating paths, drawing lines incrementally, and interpolating coordinates for shape morphing. I

react-waypoint es un componente de React y herramienta de seguimiento de viewport que ejecuta funciones basadas en la visibilidad de un nodo DOM dentro de un área desplazable. Monitorea cuándo los elementos entran o salen del viewport del navegador o de un contenedor de scroll especificado para disparar callbacks. El proyecto permite la implementación de scroll infinito, carga diferida de activos y animaciones disparadas por scroll. Permite definiciones de contenedores de scroll personalizados y configuraciones de límites de viewport usando offsets para determinar exactamente cuándo se disparan los eventos. La herramienta proporciona seguimiento de posición de elementos y monitoreo de visibilidad tanto para scroll vertical como horizontal. Incluye control de sensibilidad de disparo y limitación de eventos para gestionar la ejecución de callbacks durante el scroll rápido.
