## What it is
A lightweight, dependency-free CSS3 and JavaScript library that triggers CSS animations when elements enter the viewport during scrolling. Animations are configured via data attributes or a small JavaScript API.

## Use cases
- animate elements as they scroll into view
- add fade-in effects to page sections on scroll
- trigger CSS animations based on viewport position
- add scroll reveal animations without jQuery or frameworks
- reset animations when elements leave the viewport

## When to choose
- you want zero-dependency scroll animations in plain HTML/CSS/JS
- you prefer declarative data-attribute configuration
- you need a tiny library compatible with any stack

## When to avoid
- you need actively maintained software with recent updates
- you need advanced scroll animation features like parallax or scrubbing
- your project uses a modern framework with its own animation ecosystem

## Facets
- artifact type: library
- maturity: abandoned
- function: animation, ui-components
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: css3, scroll-animations, viewport-tracking, zero-dependencies, data-attributes
