Controls the outer and inner display type of an element, including block, inline, flex, grid, contents, and none.

Defines a border path with one or two CSS basic shapes so borders, backgrounds, clipping, and shadows can follow non-rectangular geometry. This is experimental, so use it as a progressive enhancement.
