In :before or :after pseudo-elements, the ‘display’ property can be set to “marker” to allow content to be paired with other content (usually iteratively, such as with the ‘list-style-type’ 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.
The ‘marker-offset’ property gives a horizontal distance between the marker box and the “principal” rendering box, measured between the adjacent neighboring edges of the two boxes
| Example |
| li:before { display: marker; marker-offset: 5px } |
