## What it is
A small JavaScript library that locks body scrolling on iOS, Android, and desktop browsers while preserving scrolling of a target element such as a modal, lightbox, or flyout. It works with vanilla JS and frameworks like React, Angular, and Vue.

## Use cases
- lock body scroll when a modal is open
- prevent background scrolling on iOS Safari
- keep modal content scrollable while freezing the page
- disable body scroll for lightbox overlays
- lock page scroll behind a mobile nav menu
- handle nested scrollable overlays
- reserve scrollbar width when locking scroll

## When to choose
- you need reliable body scroll locking on iOS mobile/tablet
- you want to keep a target element (modal, flyout) scrollable
- you use vanilla JS, React, Angular, or Vue
- you need nested target element support or scrollbar width reservation

## When to avoid
- you only target modern browsers with native overflow: clip support and want zero dependencies
- you need a maintained solution - the project is in maintenance with its latest release in 2023
- you need scroll locking for a specific framework with an official built-in solution
