{{APIRef("SVG")}}
The y1 read-only property of the {{domxref("SVGLinearGradientElement")}} interface describes the y-axis coordinate of the start point of the gradient as an {{domxref("SVGAnimatedLength")}}. It reflects the computed value of the {{SVGAttr("y1")}} attribute on the {{SVGElement("linearGradient")}} element.
The attribute value is a <length>, <percentage>, or <number>. The numeric value of the {{domxref("SVGAnimatedLength.baseVal")}} is the y-coordinate of the gradient's starting point in the user coordinate system.
An {{domxref("SVGAnimatedLength")}}.
Given the following SVG:
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<defs>
<linearGradient id="gradient1" x1="50%" y1="0%" x2="50%" y2="100%">
<stop offset="0%" stop-color="blue" />
<stop offset="100%" stop-color="white" />
</linearGradient>
<linearGradient id="gradient2" x1="25%" y1="0%" x2="75%" y2="100%">
<stop offset="0%" stop-color="red" />
<stop offset="100%" stop-color="yellow" />
</linearGradient>
</defs>
<rect x="0" y="0" width="200" height="100" fill="url(#gradient1)" />
<rect x="0" y="100" width="200" height="100" fill="url(#gradient2)" />
</svg>
We can access the computed values of the y1 attributes:
const linearGradients = document.querySelectorAll("linearGradient");
const y1Gradient1 = linearGradients[0].y1;
const y1Gradient2 = linearGradients[1].y1;
console.dir(y1Gradient1.baseVal.value); // output: 0 (0% of 200)
console.dir(y1Gradient2.baseVal.value); // output: 0 (0% of 200)
