## What it is
Fit.js is a tiny JavaScript library that scales and aligns one rectangular object (DOM element or plain rect) to fit inside another while preserving aspect ratio. It supports cover/contain modes, alignment options, resize watching, and custom transform callbacks.

## Use cases
- fit a video or image inside a container while keeping aspect ratio
- scale text to fill its parent element
- implement cover/contain behavior like CSS object-fit with alignment control
- refit elements automatically on window resize
- fit arbitrary rectangle objects in canvas or game layouts

## When to avoid
- you need modern CSS object-fit which covers most DOM cases
- you need responsive layout systems or grid frameworks
- the project needs actively maintained dependencies

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, graphics
- domain: web-development, frontend
- platform: browser
- tags: aspect-ratio, dom-layout, scaling, cover-contain, micro-library, javascript
