CSSimple is a utility-first, responsive, unopinionated, and open-source css framework. Some of its features are:
- Responsive flexbox grid
- Light-weight framework
- Easily modifiable using sass
- Easy to learn (semantic classes)
It was written using sass and was designed to be easily modifiable through it, instead of using the compiled css. Everything is configurable through the _config.scss file. Finally, this is an open-source project, so contributions and comments are very welcome!
