SVG Stroke Attributes

The stroke attribute sets the color of the line drawn around an element.

Here we will look at the six stroke attributes:

• stroke - sets the color of the line around an element
• stroke-width - sets the width of the line around an element
• stroke-opacity - sets the opacity of the line around an element
• stroke-linecap - sets the shape of the end-lines for a line or open path
• stroke-dasharray - sets the line to show as a dashed line
• stroke-linejoin - sets the shape of the corners where two lines meet

SVG stroke Attribute

The stroke attribute defines the color of the outline of an element.

The stroke attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke attribute can be a color name, rgb value or a hex value.

Here we use the stroke attribute to set the outline color for a polygon, rectangle, circle and a text:

Here is the SVG code:

Here we use the stroke attribute to define the color of three lines:

Here is the SVG code:

SVG stroke-width Attribute

The stroke-width attribute defines the width of the stroke.

The stroke-width attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

Here we use the stroke-width attribute to set the width of the outline for a polygon, rectangle, circle and a text:

Here is the SVG code:

Here we use the stroke-width attribute to set the width of three lines:

Here is the SVG code:

SVG stroke-opacity Attribute

The stroke-opacity attribute defines the opacity of the stroke.

The stroke-opacity attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-opacity attribute goes from 0 to 1 (or 0% to 100%).

Here we use the stroke-opacity attribute to set the opacity of the outline for a polygon, rectangle, circle and a text:

Here is the SVG code:

Here we use the stroke-opacity attribute to set the opacity of three lines:

Here is the SVG code:

SVG stroke-linecap Attribute

The stroke-linecap attribute defines different types of endings for a line or an open path.

The stroke-linecap attribute can be used with the following SVG elements: <path>, <polyline>, <line>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-linecap attribute can be "butt", "round" or "square".

Here we use the stroke-linecap attribute to set different endings for three lines:

Here is the SVG code:

SVG stroke-dasharray Attribute

The stroke-dasharray attribute is used to create dashed lines.

The stroke-dasharray attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-dasharray attribute can be "none" or a comma or space separated list of lengths/percentages that define the lengths of dashes and gaps.

Here we use the stroke-dasharray attribute to create different dashed lines:

Here is the SVG code:

Here we use the stroke-dasharray attribute to create different dashed outlines for a polygon, rectangle and a circle:

Here is the SVG code:

SVG stroke-linejoin Attribute

The stroke-linejoin attribute defines the shape of the corners where two lines meet.

The stroke-linejoin attribute can be used with the following SVG elements: <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-linejoin attribute can be "arcs", "bevel", "miter", miter-clip" or "round".

Here we use the stroke-linejoin attribute to create different corner shapes:

Here is the SVG code:
