98.css is a CSS-only design system that styles semantic HTML to look like the classic Windows 98 user interface. It ships no JavaScript, making it compatible with any frontend framework, and emphasizes accessibility.
Use cases
- build a retro Windows 98-styled website
- style a web app to look like a vintage operating system
- create a nostalgic UI mockup with CSS
- make semantic HTML look like old Windows dialogs
- add a Win98 theme to a React or vanilla JS project
When to choose
- you want pixel-faithful Windows 98 aesthetics with pure CSS
- you need a framework-agnostic stylesheet with no JavaScript dependencies
- accessibility via semantic HTML matters to your project
When to avoid
- you need a modern, production-grade design system
- you want Windows XP or Windows 7 styling instead
- you need JavaScript-powered interactive components out of the box
