Answer 1

"By default, flex items stretch to take up the full height space." Prescribe to the parentalign-items: flex-start;

Answer 2

We write to the parent element: display: flex;

Answer 3

Should child elements have a fixed height or will it grow based on the content? Can max-heightor flex-grow: 0;help?
