Web Animations Js
This project is a browser animation library and DOM animation engine that serves as a JavaScript polyfill for the Web Animations API. It provides a programmatic interface for driving visual property changes and transitions of document elements within web browsers.
The library enables programmatic UI animation and dynamic document styling using keyframes and precise timing configurations. It supports a unified interface for both standard web elements and vector graphics animation.
Features
- Web Interface Animation Libraries - Provides a programmatic interface for driving visual property changes and vector graphics animations within web browsers.
- Programmatic Animations - Controls the movement and style of webpage elements through a programmatic JavaScript interface.
- Keyframe Interpolation - Calculates intermediate visual values by interpolating between defined keyframes using specific timing functions and easing curves.
- Declarative Element Animators - Changes visual properties of DOM elements over time using a defined set of keyframes and timing options.
- JavaScript Animation APIs - Implements a JavaScript version of the Web Animations API for smooth motion and visual transitions.
- Web Animations API Polyfills - Provides a JavaScript implementation of the Web Animations API for animating document elements and web content.
- Timeline Animation Controllers - Manages animation progress through a virtual clock that supports pausing, reversing, and seeking to specific timestamps.
- Dynamic Document Styling - Changes the visual properties of HTML elements over time using keyframes and precise timing configurations.
- DOM Animation Engines - Manages timing and keyframe-based transitions of document elements through a unified JavaScript API.
- RequestAnimationFrame Loops - Syncs animation frame updates with the browser refresh rate using a recurring requestAnimationFrame loop.
- Vector Animations - Drives complex animated sequences for SVG and other vector elements using a unified programmatic interface.
- Interactive Web Animations - Drives animated content by unifying vector graphics and style animation features through a programmatic interface.
- Animation State Tracking - Tracks the current playback status, duration, and iteration count within individual animation instances.
- Style Reconciliation Systems - Computes the final visual state by merging active animation values with underlying static element styles.
- Animation Property Mapping - Translates high-level animation objects into specific CSS property updates applied directly to the element style attribute.
