## What it is
Zoomerang.js is a small drop-in JavaScript library that lets users zoom in and out on almost any element on a page, inspired by Medium's avatar zoom effect. It works via CSS transforms and keeps working when the page is resized or scrolled while zoomed in.

## Use cases
- zoom in on images when clicked
- add medium-style avatar zoom effect to my page
- magnify page elements with a click
- zoomable image lightbox without setup
- expand thumbnails to full view on click

## When to choose
- you want a zero-setup click-to-zoom effect on images or fixed-size elements
- you need a tiny dependency-free zoomer for a simple page
- you only need to support modern browsers with CSS transforms

## When to avoid
- you need IE9 or stock Android 2.x support
- your targets are long inline text with natural line wraps
- you need advanced gallery/lightbox features like captions or swipe navigation
- you need an actively maintained project

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: frontend, web-development
- platform: browser
- tags: zoom-effect, css-transforms, drop-in, medium-style-zoom, image-zoom, javascript
