Source: Style Guide
As the Buffer team grows, it will become increasingly important to maintain a consistent style and visual language across all areas of the product. To do this, we have built the following style guide to document reusable components for faster product development.
This style guide is based largely on the principles of atomic design. The key idea of this methodology is that small, independent – atomic – parts, can be combined into larger molecular structures. Molecular structures can be combined into larger organisms, which can then serve as the foundation for templates and full pages.
