/*
Body is parent of "parent", parent is parent of child, 100% means 100% of parent,
so body is by default 100% width of viewport.
Don't assign a width to a parent or child
and it's automatically responsive, then limit it later for desktop.
In practise, in most cases do not set width on child, and almost never use height.

font-size use rem, anything else use em as don't compound so no problem
