The goal of this project is to create a system that enables GitHub to build consistent user experiences with ease, yet with enough flexibility to support the broad spectrum of GitHub websites.
This is free and open source software.
Key Features
- Highly reusable, flexible styles – they can be mixed and matched to achieve many different layouts, independent of their location. They can be divided into 2 types:
- Utilities – single purpose, immutable styles, that do one thing well.
- Components – abstracted patterns for frequently used visual styles.
- Highly composable base-8 spacing scale.
- Customizable typography – Font size and line-height options work together to result in more sensible numbers. Font styles come in a range of weights and sizes so that we can style appropriately for content and readability. Change the visual styles while keeping markup semantic.
- Meaningful color – add meaningful signals to content and interactions. Color variables and utilities offer thematic styling options without being tied to structure. Text and background colors come in a range of accessible combinations to ensure we build inclusive interfaces.
