## What it is
Rellax is a lightweight, dependency-free vanilla JavaScript parallax scrolling library. It applies smooth parallax motion to elements via data attributes, with per-element speeds, responsive breakpoints, centering, and horizontal scrolling support.

## Use cases
- add parallax scrolling effects to a website
- make background images move at a different speed than the page
- create depth effects on landing pages without jQuery
- apply different parallax speeds per breakpoint
- add lightweight scroll animations to a static site

## When to choose
- you want a tiny, dependency-free parallax effect
- you need per-element speed control via simple HTML attributes
- you need responsive parallax speeds across breakpoints
- your site is plain HTML/JS without a framework

## When to avoid
- you need advanced scroll-driven animations beyond parallax
- you want scroll effects integrated into a framework like React or GSAP's ScrollTrigger
- you need performance-critical, GPU-accelerated complex animation pipelines

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, frontend-framework
- domain: web-development, frontend, web-design
- platform: browser, cross-platform
- tags: parallax, vanilla-javascript, scrolling-effects, lightweight, no-dependencies
