`<self-position>` CSS type

The <self-position> enumerated value data type is used by the justify-self and align-self properties, and the place-self shorthand, to align the box within its alignment container. It is also used by the justify-items and align-items properties, and the place-items shorthand, to specify default values for justify-self and align-self.
