## What it is
Fomantic-UI is the official community fork of Semantic-UI, a CSS and JavaScript framework for building responsive websites with human-friendly, natural-language class names. It provides a large library of UI components (buttons, forms, modals, dropdowns, etc.) with an intuitive theming system and jQuery-based behaviors.

## Use cases
- build responsive websites with semantic html classes
- style web apps with a css component framework
- add dropdowns modals and tabs to a website
- theme a ui framework with design variables
- replace semantic-ui with an actively maintained fork
- quickly prototype web layouts with prebuilt components

## When to choose
- you like Semantic-UI's natural-language class syntax and want continued maintenance
- you need a broad set of prebuilt UI components with theming support
- you're maintaining an existing Semantic-UI project

## When to avoid
- you want a React/Vue-native component library rather than jQuery-based behaviors
- you prefer utility-first CSS like Tailwind
- you need a very lightweight, minimal CSS footprint

## Facets
- artifact type: library
- maturity: active
- function: ui-components, css-framework, frontend-framework
- domain: web-development, frontend, web-design
- platform: browser, cross-platform
