## What it is
A small vanilla JavaScript library that traps keyboard focus within a DOM node, cycling Tab/Shift+Tab among its focusable elements and blocking outside clicks. It is designed for building accessible modals and dialogs, with framework wrappers like focus-trap-react available.

## Use cases
- trap focus inside an accessible modal dialog
- keep Tab key cycling within a dropdown menu or drawer
- return focus to the trigger element when a dialog closes
- block clicks outside an open popover
- build accessible keyboard navigation for custom widgets

## When to choose
- you need WAI-ARIA-compliant focus containment for modals or menus in vanilla JS or any framework
- you want a small, modular library with pause/resume and nested trap support
- you need broad browser support and a UMD build

## When to avoid
- you use React and prefer a ready-made wrapper (use focus-trap-react instead)
- you need full dialog styling, animations, or overlay behavior (this only manages focus)
- your project does not involve keyboard/focus accessibility concerns

## Facets
- artifact type: library
- maturity: stable
- function: ui-components, accessibility
- domain: web-development, frontend, accessibility
