This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.
* Some parts of this feature may have varying levels of support.
The stroke attribute is a presentation attribute defining the color (or any SVG paint servers like gradients or patterns) used to paint the outline of the shape.
Note:
As a presentation attribute, stroke also has a CSS property counterpart: stroke. When both are specified, the CSS property takes priority.
You can use this attribute with the following SVG elements:
Examples
Basic color and gradient stroke
<svg viewBox="0 0 20 10" xmlns="http://www.w3.org/2000/svg">
<!-- Basic color stroke -->
<circle cx="5" cy="5" r="4" fill="none" stroke="green" />
<!-- Stroke a circle with a gradient -->
<defs>
<linearGradient id="myGradient">
<stop offset="0%" stop-color="green" />
<stop offset="100%" stop-color="white" />
</linearGradient>
</defs>
<circle cx="15" cy="5" r="4" fill="none" stroke="url(#myGradient)" />
</svg>
The output is as follows:
context-stroke example
In this example, we define three shapes using <path> elements, each with a different stroke and fill color set on them. We also define a <circle> element as a marker via the <marker> element. Each shape has the marker applied via the marker CSS property.
The <circle> has stroke="context-stroke" and fill="context-fill" set on it. Because it is being set as a marker in the context of the shapes, these attributes cause it to inherit the fill and stroke set on the <path> element in each case.
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 300 90">
<style>
path {
stroke-width: 2px;
marker: url("#circle");
}
</style>
<path d="M 10 44.64 L 30 10 L 70 10 L 90 44.64 L 70 79.28 L 30 79.28 Z"
stroke="red" fill="orange" />
<path d="M 100 44.64 L 80 10 L 120 10 L 140 44.64 L 120 79.28 L 80 79.28 Z"
stroke="green" fill="lightgreen" />
<path d="M 150 44.64 L 130 10 L 170 10 L 190 44.64 L 170 79.28 L 130 79.28 Z"
stroke="blue" fill="lightblue" />
<marker id="circle" markerWidth="12" markerHeight="12"
refX="6" refY="6" markerUnits="userSpaceOnUse">
<circle cx="6" cy="6" r="3" stroke-width="2"
stroke="context-stroke" fill="context-fill" />
</marker>
</svg>
The output is as follows:
Note:
Elements can also use context-stroke and context-fill to inherit stroke and fill values when they are referenced by <use> elements.
