CSS width and height does not include the border(s) and padding by default. box-sizing: border-box include them in the border.
The browser calculate a box with max-content as if it has infinite space. For min-content, it pretends it has zero space. Easy at the end !
min, max and clamp define boundaries for the box :) Clamp is simply a min-max combined into one: clamp(MIN, VAL, MAX)
