## What it is
MUI is a lightweight CSS framework implementing Google's Material Design guidelines, with a small gzipped footprint (~6.6K CSS, ~5.4K JS) and no external dependencies. It ships variants for plain web, React, Angular, WebComponents, and HTML email styling, plus RTL, no-globals, and rem-based builds.

## Use cases
- style a website with material design css
- lightweight css framework for a small site
- responsive grid for mobile-friendly pages
- material design components for react
- style html emails with material design
- rtl css framework for arabic or hebrew sites
- customize material design colors with sass

## When to avoid
- you need a full-featured modern component library with active development
- you want React Material UI (MUI v5) - this is a different project
- you need recent browser features or ongoing updates, since releases stopped in 2021
