Pure is a minimal, responsive CSS library that provides a set of small, modular styles for base HTML elements, grids, buttons, forms, menus, and tables. It builds on Normalize.css for cross-browser consistency and follows SMACSS conventions for easy customization. The repository contains the source CSS files, a Grunt-based build system that generates minified and prefixed bundles, and a Docusaurus documentation site. The library is production-ready, extremely lightweight (3.7KB gzipped), and designed to be a starting point for any web project without imposing a specific look.
The LLM identified 3 files worth highlighting for reuse:
Provides the core grid system using CSS Flexbox. The `.pure-g` class sets up a flex container with row wrapping and `align-content: flex-start` to prevent space distribution. The `.pure-u` class makes child elements inline-block with vertical alignment. This minimal, well-commented CSS is the foundation for Pure's responsive grid and can be extracted to create a custom grid system in any project.
Implements dropdown submenus with absolute positioning and arrow indicators. Uses `:after` pseudo-elements on `.pure-menu-has-children > .pure-menu-link` to add a right-pointing arrow for vertical menus and a down-pointing arrow for horizontal menus. The `.pure-menu-children` are hidden by default and shown on hover (with `.pure-menu-allow-hover`) or when active. This pattern is self-contained and demonstrates clean CSS-only dropdowns without JavaScript.
A Node.js module that provides helper functions for the documentation site. It reads Pure's built CSS files, calculates gzipped sizes for each module, generates an SRI hash for the CDN snippet, and exports a `PURE_DOWNLOAD_SNIPPET` string. The `moduleSizes()` function uses `fs` and `gzip-size` to produce a map of module names to compressed sizes. This utility is reusable for any project that needs to analyze CSS bundle sizes and generate integrity hashes.
