This repository is a Tailwind CSS plugin that generates utility classes for fixed aspect ratios using the 'padding-bottom trick' for browser compatibility (particularly Safari 14). The plugin provides composable classes like `aspect-w-{n}` and `aspect-h-{n}` that set CSS custom properties to define the width and height ratio, along with `aspect-none` to remove the ratio. It supports both Tailwind CSS v2 (via `addComponents`) and v3 (via the newer `matchComponents` API, which also enables arbitrary values). The codebase is minimal: a single source file (`src/index.js`) that exports a plugin configuration, a TypeScript type declaration, and a Jest test suite that validates CSS output for both versions. As noted in the README, Tailwind CSS v3.0 ships with native `aspect-ratio` utilities, making this plugin obsolete for most projects; it remains useful only for projects requiring Safari 14 support. The implementation is clean, well-structured, and follows Tailwind's official plugin authoring patterns, but offers no surprising craftsmanship or reusable components beyond its designated purpose.
