The compass core framework is a design-agnostic framework that provides common code that would otherwise be duplicated across other frameworks and extensions.

Bourbon is a library of pure sass mixins that are designed to be simple and easy to use. No configuration required. The mixins aim to be as vanilla as possible, meaning they should be as close to the original CSS syntax as possible.

It is a CSS file in which all class names and animation names are scoped locally by default. The key words here are scoped locally. With this, your CSS class names become similar to local variables in JavaScript. It goes into the compiler, and CSS comes out the other side.

It is a library that provides binding for Node.js to LibSass, the C version of the popular stylesheet preprocessor, Sass. It allows you to natively compile .scss files to css at incredible speed and automatically via a connect middleware.

It is less than 1KB css-in-js solution. It is built on the shoulders of well-established solutions. That means the API has been paved and we just need to follow it.

It is a fully-typed CSS-in-JS library featuring near-zero runtime, server-side rendering, multi-variant support, and a best-in-class developer experience.

It combines Sass-like syntactical sugar — like variables, conditionals, and iterators — with emerging CSS features — like logical and custom properties, media query ranges, and image sets.

It is a new CSS parser, compiler, and minifier written in Rust. It has significantly better performance than existing tools, while also improving minification quality. It handles compiling CSS modules, tree shaking, automatically adding and removing vendor prefixes for your browser targets, and transpiling modern CSS features like nesting, logical properties, level 4 color syntax, and much more.

It is an implementation of the CSS (Cascading Style Sheet) parsing algorithm implemented as a pure C library with no outside dependencies. It's designed to serve as a building block for other tools and libraries such as linters, validators, templating languages, and refactoring and analysis tools.

It is a CSS-in-JS engine with near-zero runtime and ahead-of-time compilation. SSR support and styles are defined with JavaScript objects. You can simply install and use it in code directly.
