What it is

98.css is a CSS file that styles standard HTML elements so they resemble the classic Windows 98 user interface. It contains no JavaScript, so it can be used alongside any frontend framework. People use it to build retro-styled windows, dialogs, and buttons for websites or design projects.

  • Style a dialog box with a title bar, window body, and buttons using a single CSS file
  • Recreate an old Windows 98 program window inside a web page
  • Prototype a retro-themed interface in plain HTML before adding a framework

Great for

  • Web developers making a retro or nostalgic website
  • Designers who want Windows 98-style mockups in HTML
  • Developers who want a stylesheet with no JavaScript dependency
  • Anyone building a novelty or joke app in an old Windows look

Not ideal for

  • Projects needing a modern, general-purpose UI kit, since it only mimics the Windows 98 look
  • Teams that need accessibility guarantees, since the README does not discuss accessibility

Strengths

  • Single CSS file with no JavaScript, so it fits into any frontend stack
  • Available via unpkg, npm, and GitHub releases

Trade-offs

  • Only covers the Windows 98 visual style, not general layout or components beyond what it styles
  • The README is brief on component details and points to an external documentation site for those
