SVGLinearGradientElement: y1 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 y1 read-only property of the SVGLinearGradientElement interface describes the y-axis coordinate of the start point of the gradient as an SVGAnimatedLength. It reflects the computed value of the y1 attribute on the <linearGradient> element.

The attribute value is a <length>, <percentage>, or <number>. The numeric value of the SVGAnimatedLength.baseVal is the y-coordinate of the gradient's starting point in the user coordinate system.

Value

An SVGAnimatedLength.

Example

Given the following SVG:

html

<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)
