offset-anchor
CSS offset-anchor property
The offset-anchor property defines the anchor point of a box along the offset path. An offset path is considered to be either a geometry of a basic shape that hasn’t been styled or a path consisted of one or more sub-paths. The anchor point specifies the point of the box which is the point that is moved along the offset path.
This offset property is an experimental technology.
