stroke-dasharray
CSS stroke-dasharray Property
The stroke-dasharray property takes control over the pattern of dashes and gaps used to form the shape of a path’s stroke.
The stroke-dasharray property has two values: none and <dasharray>.
A <dasharray> is a list of comma and/or white space separated lengths or percentages. Each value specifies a length along the path for which the stroke is a dash or a gap.
The presentation attribute will be overridden: e.g. <path stroke-dasharray=“4” … />. The inline style won’t be overridden: e.g. <path style=“stroke-dasharray: 4;” … />.
The stroke-dasharray property can be used as a CSS property as a presentation attribute. It can be applied to any element but can have an effect only on the following elements: <altGlyph>, <circle>, <ellipse>, <path>, <line>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref>, and <tspan>.
