## What it is
A JavaScript polyfill that implements the CSS Grid Layout specification in browsers lacking native support, including IE 9+. It parses stylesheets, supports grid features like areas, fr units, and automatic placement, and reacts to DOM changes, media queries, and pseudo-classes.

## Use cases
- use css grid layout in internet explorer
- polyfill css grid for older browsers
- prototype css grid layouts before native support
- support grid layout in legacy browsers
- test css grid features in ie9

## When to choose
- you must support IE 9+ or other browsers without native CSS Grid
- you need a quick prototyping shim for grid layouts

## When to avoid
- your target browsers support CSS Grid natively (all modern browsers do)
- you need an up-to-date, spec-compliant implementation - the project is unmaintained and outdated
