Skrollr is a dependency-free scroll-driven animation engine and cross-platform frontend library. It functions as a toolkit for linking CSS properties and HTML attributes to scroll positions to create synchronized animations, specifically providing utilities for the interpolation of SVG attributes. The library enables the creation of parallax scrolling and interactive web storytelling by mapping scroll offsets to specific style values. It allows for the development of non-linear movement and dynamic SVG effects through the use of custom HTML attributes that define keyframes. The system covers
Scrollama is a JavaScript library for scroll-driven storytelling that uses the browser's native IntersectionObserver API to trigger step-based callbacks and animations as the user scrolls through a page. It pins graphic elements using CSS sticky positioning while scrolling through associated text steps, enabling side-by-side narrative experiences without JavaScript-driven layout calculations. The library provides a configurable offset threshold system that accepts a single global offset or per-element data-attribute offsets to define the viewport position that triggers step events. It reports
MJRefresh is a scroll view interaction library and a set of reusable UI components for implementing pull-to-refresh and infinite scrolling behaviors in mobile user interfaces. It provides customizable refresh indicators and controllers that manage reload callbacks and loading states within scrollable containers. The library allows for the replacement of standard loading indicators with custom images, GIF sequences, and status labels to match specific visual branding. It includes a global configuration store to handle dynamic UI localization and the translation of refresh content across an app
Waypoints is a JavaScript library designed for monitoring scroll positions and managing viewport-based triggers. It provides utilities to execute functions when page elements enter or exit the visible browser area, track specific scroll offsets, and implement sticky element pinning. The library includes specialized tools for building infinite scrolling interfaces that fetch and append content to replace traditional pagination. It also manages the positioning of elements that transition to a fixed screen location once a specific scroll threshold is reached. The system covers broader capabilit
headroom.js is a client-side JavaScript header visibility controller and DOM manipulator. It functions as a scroll-based UI component that hides page headers during downward scrolls and reveals them during upward scrolls to maximize available viewport space.
