Egeo UI Base is a framework of Sass utilities to be used in an Egeo-based project. It is part of the Egeo project. However, it has no problems to be used in any other project. The framework includes a series of APIs to obtain the colors, typography parameters, a grid based in the flexboxgrid fully rewritten in Sass and much more every application should have. This library is designed thought in Stratio's needs but any developer could fork it or use it for its own needs or, better, suggest new features to be implemented in the future.
