The div which has less “vertical content” (so to speak) needs to match the height of the other div.
I am essentially using the code from this w3 lesson: https://www.w3schools.com/howto/howto_css_zig_zag_layout.asp
The only solution I can think of is manually setting a
height for each row (the parent element) and setting the divs to
Flexbox align-items: stretch seems to do the trick
