## What it is
7.css is a JS-independent, tree-shakeable CSS framework that styles semantic HTML to faithfully recreate the Windows 7 (Aero) user interface. Built on top of XP.css and 98.css, it works with any frontend framework since it ships no JavaScript.

## Use cases
- build a retro Windows 7 style web interface
- style HTML components to look like Windows 7 Aero UI
- create a nostalgic win7-themed website without JavaScript
- make a fake Windows 7 desktop in the browser
- theme a web app with Windows 7 look and feel
- recreate old Windows UI components like windows, title bars, and dialogs

## When to choose
- you want pixel-faithful Windows 7 styling with pure CSS and no JavaScript dependency
- you need framework-agnostic styling that works with Vue, Svelte, React, or plain HTML
- you want accessible, semantic-HTML-based retro UI components
- you need scoped styles that coexist with another CSS framework

## When to avoid
- you need a modern, native-looking design system rather than a retro Windows 7 aesthetic
- you need interactive components with built-in behavior, since 7.css provides styling only
- you want Windows XP, 98, or other OS themes - use XP.css or 98.css instead
