Straight up raw CSS Grid is my new favorite. It let's you do what we used to do with tables. It even improves it with fr units. Though not sure what to do with the extra brain cycles that don't goto div soup layouts.

Me too. I can't get my head around all the properties for Flexbox, but CSS Grid makes everything so simple.

My latest trick is to swap around the "cells", without changing the HTML markup (generated by simple_form Ruby gem).
