Need CSS to change content alignment on mobile for Squarespace 7.1

Hello, SS Jedi Masters: I need a CSS snipped, for 7.1, to change the content alignment in the intro section of my portfolio site.

Right now it's set to bottom margin. But on mobile I need to change alignment to top margin. (This is mobile only; desktop is all set). 

I've tried a couple things, but haven't found the solution yet. 

As an alternative I could also change the section height on mobile only. Have tried but so far no success on this solution, as well. 

Thanks very much!

Did you solve?
