## What it is
Sal (Scroll Animation Library) is a lightweight, dependency-free JavaScript library for animating elements as they scroll into the viewport. It uses the Intersection Observer API for high performance and is configured via simple data attributes in HTML.

## Use cases
- animate elements on scroll
- add fade or slide effects when elements enter the viewport
- lightweight scroll reveal animations without jQuery
- performant scroll-triggered animations using Intersection Observer
- add entrance animations to a landing page
- customize animation duration, delay, and easing via data attributes

## When to choose
- you need a tiny (<3 kb), zero-dependency scroll animation solution
- you want simple declarative setup with data attributes
- performance matters and you want to leverage Intersection Observer
- you only need basic fade, slide, zoom, and flip entrance animations

## When to avoid
- you need advanced scroll-linked or parallax animations, not just entrance reveals
- you must support very old browsers without Intersection Observer and don't want a polyfill
- you want a full-featured animation engine like GSAP with timelines and keyframes
- you need actively developed software with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: frontend, web-development
- platform: browser
