tachyons

Tachyons is a functional CSS framework designed for humans who want to build and design user interfaces quickly without writing traditional CSS. It provides a set of single-purpose, composable utility classes that cover layout, spacing, typography, color, and more, enabling developers to style elements directly in HTML. Key principles include full responsiveness, readability on any device, fast performance, ease of designing in the browser, and the ability to change interfaces without breaking existing ones. The framework emphasizes reusability, minimal code sent to users, and accessibility. Features include a mobile-first CSS architecture, 490 accessible color combinations, an 8px baseline grid, debugging utilities, a single-purpose class structure, optimized gzip compression, lightweight size (~14kB), and compatibility with plain HTML, React, Ember, Angular, Rails, and more. It also offers an infinitely nestable responsive grid system and is built with PostCSS. Getting started is simple: include the minified CSS from a CDN or clone the repository and install via npm. Developers can build and watch for changes with npm scripts, and a linter helps detect class redefinitions or naming collisions. Documentation is available at tachyons.io, with an open-source docs repository. Community resources include learning guides, quick reference tools, and quizzes. The project encourages contributions and showcases production sites like npmjs.com and others. For help, users can open issues or join the Tachyons Slack channel.
