## What it is
A Grunt task that converts a set of images into a spritesheet and generates corresponding CSS variables for formats like CSS, SASS, SCSS, LESS, Stylus, and JSON. It supports retina spritesheets and works cross-platform on Windows, Linux, and macOS.

## Use cases
- generate a css spritesheet from a folder of icons
- create sprite variables for sass or less
- build retina @2x spritesheets with grunt
- automate image sprite generation in a grunt build
- convert icons into a single image with css offsets

## When to avoid
- you use Gulp, Webpack, or another modern bundler instead of Grunt
- you prefer inline SVG or icon fonts over image spritesheets
- you need a build system without a maintained Grunt setup

- domain: web-development, frontend, image-processing, developer-tools
