Flexbox would have been my preference here. media query to switch the flex-direction, order to pull the buttons up in small mode. But grid seems to work too.

I've been doing this for 20+ years. I was there when CSS hatched and we started switching out tables and image maps for divs and layers and then crying when IE4, IE5 invariably didn't work. What I mean to say is that isn't is nice that we can have multiple ways of accomplishing the same thing in a standard way?

I barely ever have to fix cross-browser positional issues these days. That used to be 20% of my working life.
