<display-outside>

The <display-outside> keywords specify the element's outer display type, which is essentially its role in flow layout. These keywords are used as values of the display property, and can be used for legacy purposes as a single keyword, or as defined in the Level 3 specification alongside a value from the <display-inside> keywords.
