{{SVGRef}}

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` can be used as a CSS property. See {{cssxref('stroke')}} for more.

You can use this attribute with the following SVG elements:

- {{SVGElement('circle')}}
- {{SVGElement('ellipse')}}
- {{SVGElement('line')}}
- {{SVGElement('path')}}
- {{SVGElement('polygon')}}
- {{SVGElement('polyline')}}
- {{SVGElement('rect')}}
- {{SVGElement('text')}}
- {{SVGElement('textPath')}}
- {{SVGElement('tref')}}
- {{SVGElement('tspan')}}

## Examples

### Basic color and gradient stroke

```css hidden
html,
body,
svg {
  height: 100%;
}
```

```html
<svg viewBox="0 0 20 10" xmlns="http://www.w3.org/2000/svg">
  <!-- Simple 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 {{SVGElement('path')}} elements, each with a different `stroke` and [`fill`](/en-US/docs/Web/SVG/Attribute/fill) color set on them. We also define a {{SVGElement('circle')}} element as a marker via the {{SVGElement('marker')}} element. Each shape has the marker applied via the `marker` CSS property.

The {{SVGElement('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 {{SVGElement('path')}} element in each case.

```html-nolint
<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:

{{EmbedLiveSample("`context-stroke` example", '100%', 220)}}

> [!NOTE]
> Elements can also use `context-stroke` and `context-fill` to inherit `stroke` and `fill` values when they are referenced by {{SVGElement('use')}} elements.

    </tr>
    <tr>
      <th scope="row">Default value</th>
      <td><code>none</code></td>
    </tr>
    <tr>
