SVGPatternElement: href property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The example demonstrates how the href attribute in the <pattern> element references another pattern (#basePattern) to apply its design to a rectangle.
