Css
This project is a CSS design system framework and modular library providing a standardized set of UI component stylesheets. It establishes a unified system of visual guidelines to ensure a consistent and professional look and feel across web interfaces.
The framework is organized as a collection of standalone stylesheets that can be imported individually to minimize bundle size and eliminate unused styles. It utilizes a design token system based on CSS variables to manage theming and a utility-first class system for layout and spacing.
The system employs a block element modifier naming convention to maintain predictable specificity and organizes styles into independent files per component. It leverages Sass for style composition and distributes pre-compiled static assets to remove the need for a build step in consuming applications.
