I thought I'd share a new project I just launched today. It is a multimethod grid system library, built with flexbox and CSS grid. Open source under the MIT license, so feel free to use it in any projects you wish.

It will be used in future versions of my larger Brutalist Framework project (which I plan to build a new theme for the Concrete CMS marketplace with it in the near future).
