{{APIRef("SVG")}}
The href read-only property of the {{domxref("SVGPatternElement")}} interface reflects the {{SVGAttr("href")}} or {{SVGAttr("xlink:href")}} {{deprecated_inline}} attribute of the given element.
An {{domxref("SVGAnimatedString")}} object.
The example demonstrates how the href attribute in the {{SVGElement("pattern")}} element references another pattern (#basePattern) to apply its design to a rectangle.
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<defs>
<!-- First pattern definition -->
<pattern
id="basePattern"
width="20"
height="20"
patternUnits="userSpaceOnUse">
<circle cx="10" cy="10" r="10" fill="blue" />
</pattern>
<!-- Second pattern referencing the first -->
<pattern id="pattern1" href="#basePattern" />
</defs>
<rect x="50" y="50" width="100" height="100" fill="url(#pattern1)" />
</svg>
