SVGRadialGradientElement: fx property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The fx read-only property of the SVGRadialGradientElement interface describes the x-axis coordinate of the focal point of the radial gradient as an SVGAnimatedLength. It reflects the computed value of the fx attribute on the <radialGradient> element.

The attribute value is a <length>, <percentage>, or <number>. The numeric value of the SVGAnimatedLength.baseVal is the x-coordinate of the focal point of the radial gradient in the user coordinate system.

Value

Example

Given the following SVG:

html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <radialGradient id="gradient1" cx="50" cy="75" fx="30" fy="60" r="30">
      <stop offset="0%" stop-color="blue" />
      <stop offset="100%" stop-color="white" />
    </radialGradient>
    <radialGradient id="gradient2" cx="25%" cy="50%" fx="10%" fy="40%" r="10%">
      <stop offset="0%" stop-color="red" />
      <stop offset="100%" stop-color="yellow" />
    </radialGradient>
  </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 fx attributes:

js
const radialGradients = document.querySelectorAll("radialGradient");
const fxGradient1 = radialGradients[0].fx;
const fxGradient2 = radialGradients[1].fx;

console.dir(fxGradient1.baseVal.value); // output: 30
console.dir(fxGradient2.baseVal.value); // output: 20 (10% of 200)
