Terminal CSS is a modern, lightweight, and minimal pure CSS framework designed for developers, bloggers, and terminal lovers who want a retro console aesthetic for their web projects. Inspired by hack.css and created by Jonas Duri, it provides a full suite of terminal-styled UI components without any JavaScript overhead.

The main features and capabilities of the framework include:

• Ultra-Lightweight & Zero Overhead: Built with pure CSS and zero dependencies, weighing in at only ~3k gzip for fast loading.

• Flexible Installation: Can be installed directly into front-end build pipelines via npm (npm i terminal.css) or linked directly via CDN stylesheet.

• Theme Presets & CSS Custom Properties: Offers Light, Dark, Sans, and Sans Dark theme variations, and allows easy customization by overriding CSS variables (such as --global-font-size, --font-stack, --primary-color, --background-color, and --block-background-color).

• Terminal Component Library: Features pre-styled terminal elements, including navigation bars, navigation lists, form inputs, buttons (Primary, Error, Ghost, and Button Groups), cards, timelines, alerts, progress bars, tables, and a single-depth Table of Contents (TOC) component.

• Single-Font Typography Model: Applies a unified monospaced font stack across all elements when using <body class="terminal"> for an authentic terminal feel.

• Built-in Code Highlighting: Comes pre-packaged with a custom theme for Highlight.js to render syntax-highlighted code blocks.

• AI-Assisted Documentation: Includes a custom ChatGPT assistant trained on the framework's documentation and source code to answer setup questions.
