The display-outside CSS property specifies the outer display type of the box generated by an element, dictating how the element participates in its parent formatting context.
These display types require their parent and children to be of particular display types. For example, a table-row box requires its parent to be a table row group box and its children to be table-cell boxes.
These display types require their parent to be of a particular display type, but can accept any display-inside value. For example, a table-caption box must have a table parent, but can establish any kind of formatting context for its children.
