fractures is a CSS toolkit built by @pyx that may be used for quick prototyping as well as for production. The project consists of a library providing a set of CSS utility classes for handling spacing, grids, alignment and even typography in a matter of seconds.
The good thing about fractures is that it is atomic, non blocking: in other words it leaves UI untouched and you can use it in combination with any other existing CSS framework. Yeah, that’s cool.
