SVG <feDropShadow> Element

SVG stands for Scalable Vector Graphic. It can be used to make graphics and animations like in HTML canvas. The <feDropShadow> element works in combination with other filter primitives to add a drop shadow to the graphic. It provides a blurred, colored, and optional offset layer behind the original input.

Syntax:

<feDropShadow in="" dx="" dy="" stdDeviation=""/>

Attributes:

in: It identifies input for the given filter primitive.
dx, dy: It defines the shift in the position of the element in its respective x, y-axis.
stdDeviation: It defines the amount of blur applied to the drop shadow. The default value is 0.
