## What it is
Micromodal.js is a tiny (~1.8kb), dependency-free JavaScript library for creating accessible modal dialogs that comply with WAI-ARIA guidelines. It handles aria attribute toggling, focus trapping, escape/overlay closing, and focus restoration with minimal configuration.

## Use cases
- add accessible modal dialogs to a website
- trap keyboard focus inside a modal
- make modals screen-reader friendly with aria attributes
- close dialogs on escape key or overlay click
- support nested modals in vanilla javascript
- add modals without a heavy framework or dependencies

## When to choose
- you need WAI-ARIA compliant modals in a plain JavaScript or framework-free project
- bundle size matters and you want a sub-2kb solution
- you want focus trapping and focus restoration handled for you out of the box
- you need nested modal support with minimal configuration

## When to avoid
- your framework already provides a built-in accessible dialog component (e.g. Radix, Headless UI)
- you need highly complex modal workflows like multi-step wizards with state management
- you require IE11 support without adding the suggested polyfill
- you need a full component library rather than a single-purpose modal utility

## Facets
- artifact type: library
