## What it is
XP.css is a CSS framework that styles semantic HTML to look like Windows XP and Windows 98 interfaces. It is a JavaScript-free extension of 98.css, making it compatible with any frontend framework.

## Use cases
- make a website look like Windows XP
- recreate retro operating system UIs in the browser
- style semantic HTML like Windows 98 dialogs
- build a nostalgic fake OS web app
- add retro window and button styling to a React app
- create a themed UI without JavaScript

## When to choose
- you want pixel-faithful Windows XP or 98 styling with pure CSS
- you need a framework-agnostic stylesheet that works with React, Vue, or vanilla HTML
- accessibility via semantic HTML is a priority

## When to avoid
- you need modern, production-grade design system components
- you require JavaScript behaviors like draggable windows out of the box
- your project needs themes for operating systems other than XP or 98

## Facets

- domain: web-development, frontend, web-design
