Primer
Primer is a CSS design system framework and utility library used to build consistent user interfaces based on a unified visual language. It provides a collection of CSS rules, utility classes, and pre-defined style sheets for styling standard interface elements.
The framework implements frontend visual standardization through a shared set of utility classes and design system rules. This allows for the creation of reusable interface elements and the rapid development of web interface layouts.
The system utilizes a BEM-based naming convention, design-token mapping, and CSS variable-based theming. It is built using Sass-based module compilation to organize styles into component-specific stylesheets and utility-first classes.
