Marker-offset

The CSS   property gives a horizontal distance between the marker box and the "principal" rendering box, measured between the adjacent neighboring edges of the two boxes. In  or   pseudo-elements, the   property can be set to   to allow content to be paired with other content (usually iteratively, such as with the   property behavior). An element's content creates a "principal" rendering box. The "marker" for the "principal" box should be formatted in a single-line outside the "principal" box. The "marker" box should allow the border and padding properties, but not margins.
