SVGFEFloodElement: y property

The y read-only property of the SVGFEFloodElement interface describes the vertical coordinate of the position of an SVG filter primitive as a SVGAnimatedLength.

It reflects the y attribute of the <feFlood> element, which fills an SVG filter subregion with the color and opacity defined by flood-color and flood-opacity. The attribute is a <length> or <percentage>. The <coordinate> is a length in the user coordinate system that is the given distance from the origin of the filter along the y-axis. If the y attribute is a percent value, the property value is relative to the height of the filter region in user coordinate system units. The default value is 0.

Value

An SVGAnimatedLength.

Example

const feFlood = document.querySelector("feFlood");
const topPosition = feFlood.y;
console.log(topPosition.baseVal.value); // the `y` value
