## What it is
A tiny (0.7 kB gzipped) JavaScript library that wraps the browser Fullscreen API, normalizing vendor-prefixed implementation differences. It lets web developers request, exit, and toggle fullscreen mode for the page or any element with a simple, consistent API.

## Use cases
- make a webpage go fullscreen with a button click
- toggle fullscreen on an image or video element
- hide mobile navigation UI when entering fullscreen
- avoid writing cross-browser fullscreen vendor prefix code
- check whether fullscreen is supported before requesting it

## When to choose
- you need reliable cross-browser fullscreen behavior in a web app
- you want a tiny dependency-free-feeling ESM utility instead of hand-rolled vendor prefix handling
- you need to fullscreen arbitrary DOM elements, not just the page

## When to avoid
- you need to support iPhone Safari, which does not support the Fullscreen API
- you need new features beyond the current API, since the package is feature-complete
- you cannot use ESM and don't want to pin the older 5.2.0 version

## Facets

- maturity: maintenance
- function: ui-components, developer-tools
- domain: web-development, frontend, browser-extensions
