Should I use Grid or Flexbox?
Two sentences from Rachel Andrew that explain when to reach for which layout choice:
Flexbox is essentially for laying out items in a single dimension – in a row OR a column. Grid is for layout of items in two dimensions – rows AND columns.
Flexbox can wrap, making it sorta-kinda two dimensions, but it still flows in a single dimension.
