SVGFEDropShadowElement: dy 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 dy read-only property of the SVGFEDropShadowElement interface reflects the dy attribute of the given <feDropShadow> element.

Value

An SVGAnimatedNumber object.

Examples

Accessing the dy value

In this example, we retrieve the vertical shift of the <feDropShadow> by using the dx read-only property of the SVGFEDropShadowElement interface.
