marker

The marker CSS property points to a marker that will be drawn on the first, middle, and last vertices of the element’s path; that is, at all of its vertices. The marker must have been defined using an SVG marker element, and can only be referenced with a <url> value. The value of the CSS property overrides any values of the marker-start, marker, and marker-end attributes in the SVG.

For many marker-supporting shapes, the first and last vertices are in the same place: for example, the top left corner of a rect. In such shapes, if both the first and last markers are defined, two markers will be drawn at that point, though they may not point in the same direction.

Syntax example: marker: none;
