Bolts
v1.0.1
Bolts is a collection of practical Sass mixins and JS functions helping you deal with all the mundane website building and styling tasks, so that you can focus on creating something new. It aims to be a toolkit that does the things you're tired of.
Bolts does not output any unnessecary styles and all functions can be loaded separately through ES6 imports, making its footprint as tiny as possible.
