CSS stroke-dasharray Property

❮ Prev Next ❯

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;" ... />.
