## What it is
simpleParallax.js is a lightweight TypeScript library that adds parallax scroll effects directly to <img> tags, available for both React and vanilla JavaScript. It works out of the box with React, Next.js, and plain JS, requiring no background images.

## Use cases
- add parallax scrolling effect to images on a website
- animate images on scroll in a React app
- apply parallax to img tags without background images
- create scroll-driven image animations in Next.js
- add depth effects to hero images on a landing page

## When to choose
- you want a simple, lightweight parallax effect on image tags
- you use React or Next.js and want a drop-in parallax component
- you need a vanilla JS parallax solution with TypeScript types
- you want configurable orientation, scale, and delay for scroll animations

## When to avoid
- you need parallax on background images or full sections rather than img tags
- you need complex multi-layer or mouse-driven parallax effects
- your project does not use scroll-based image animations
