## What it is
Mobi.css is a lightweight, mobile-first CSS framework weighing only 3kb gzipped, built with PostCSS. It features a plugin system that allows plugins to be used standalone or to extend the core framework.

## Use cases
- build a lightweight mobile-first webpage
- style a content-rich mobile site with minimal CSS
- use a small CSS framework instead of Bootstrap
- extend a CSS framework with plugins
- build responsive pages that also look good on desktop

## When to choose
- you need a tiny (~3kb) CSS foundation for mobile-first content pages
- you want a plugin-based CSS architecture with standalone plugin usage

## When to avoid
- you need a modern, actively maintained framework
- you require a large component library or utility-class ecosystem
- your project depends on long-term support and recent browser features

## Facets
- artifact type: library
- maturity: abandoned
- function: css-framework, ui-components
- domain: web-development, frontend, web-design, mobile-development
- platform: cross-platform
- tags: mobile-first, flexbox, postcss, lightweight, plugin-system, web-server
