Elemental UI Framework

Elemental is an open-source React & CSS UI Framework designed for building web applications, developed by Thinkmill. The project's latest version is 0.6.1, and its primary focus was to provide a modular set of UI components built to natively implement React patterns, particularly for use with KeystoneJS. While the original vision included being 'currently under development' and responsive to feedback for API experimentation and styling transitions, the project has not seen updates since around 2017, making it effectively abandoned. It supported older React versions (0.14 and 15) and leveraged LESS for styling, requiring a LESS compiler in the build process. Key differentiators included its unopinionated default style and flexible theming capabilities, built upon React.js, LESS, Babel, and Gulp.
