## What it is
Susy is a design-agnostic Sass/SCSS library of functions for building custom responsive grid layouts, created before flexbox and CSS Grid were widely available. It is now officially deprecated and receives no further updates.

## Use cases
- build custom responsive grid layouts in Sass
- calculate grid math for float or flexbox layouts
- create grids-on-demand without a strict framework
- maintain a legacy project that already uses Susy
- study well-crafted Sass function design

## When to choose
- you are maintaining an existing codebase that already depends on Susy
- you need grid math helpers for a legacy Sass project on old tooling
- you want to study its source as a reference for Sass function design

## When to avoid
- starting any new project - it is deprecated and unmaintained
- modern layouts that can use native CSS Grid or flexbox
- teams needing long-term support or bug fixes

## Facets
- artifact type: library
- maturity: abandoned
- function: css-framework, ui-components
- domain: web-development, frontend, web-design
- platform: cross-platform
- tags: sass, scss, grid-system, responsive-layout, deprecated, css-grid, layout-engine, nodejs, web-server
