Tachyons is a functional (utility-first) CSS toolkit of small, single-purpose, composable classes for building responsive UIs without writing custom CSS. It ships a lightweight ~14kB stylesheet usable via CDN or npm, built with PostCSS and organized into small readable modules.

Use cases

• rapidly prototype web UIs without writing CSS
• build responsive mobile-first interfaces with utility classes
• create a consistent design system across projects
• minimize CSS payload sent to users
• style plain HTML, React, Angular, or Rails apps with the same classes
• debug and inspect layout issues in the browser

When to choose

• you want utility-first CSS with a tiny footprint and excellent gzip compression
• you prefer composing single-purpose classes over writing semantic CSS
• you need a mobile-first, responsive framework that works with any JS framework or plain HTML
• you want an easy-to-read, modular CSS codebase you can customize and rebuild

When to avoid

• you prefer component-scoped or semantic class naming over utility classes
• your team relies on a design system requiring heavy theming out of the box
• you need a large prebuilt component library rather than low-level building blocks
• you want a framework with frequent active development and new features
