What is the primary consequence of setting the ‘display’ property to ‘contents’ on a container element?

Accepted Answer

When 'display: contents' is applied, the element itself does not generate any boxes. Instead, its children are promoted to the parent's level in the layout hierarchy. This is useful for styling nested structures without adding extra DOM nodes that interfere with flexbox or grid layouts. It does not hide the element in the way 'display: none' does, as the children remain visible and functional.
