XP.css

XP.css is an extension of 98.css. A CSS library for building interfaces that look like old UIs.

This library relies on the usage of semantic HTML. To make a button, you'll need to use a <button>. Input elements require labels. Icon buttons rely on aria-label. This page will guide you through that process, but accessibility is a primary goal of this project.

You can override many of the styles of your elements while maintaining the appearance provided by this library. Need more padding on your buttons? Go for it. Need to add some color to your input labels? Be our guest.

This library does not contain any JavaScript, it merely styles your HTML with some CSS. This means 98.css is compatible with your frontend framework of choice.
