{{SVGRef}}

The SVG <feDropShadow> filter primitive creates a drop shadow of the input image. It can only be used inside a {{SVGElement('filter')}} element.

Note: The drop shadow color and opacity can be changed by using the {{SVGAttr('flood-color')}} and {{SVGAttr('flood-opacity')}} presentation attributes.

Example

html,
body,
svg {
  height: 100%;
}

<svg viewBox="0 0 30 10" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <filter id="shadow">
      <feDropShadow dx="0.2" dy="0.4" stdDeviation="0.2" />
    </filter>
    <filter id="shadow2">
      <feDropShadow dx="0" dy="0" stdDeviation="0.5" flood-color="cyan" />
    </filter>
    <filter id="shadow3">
      <feDropShadow
        dx="-0.8"
        dy="-0.8"
        stdDeviation="0"
        flood-color="pink"
        flood-opacity="0.5" />
    </filter>
  </defs>

  <circle cx="5" cy="50%" r="4" style="fill:pink; filter:url(#shadow);" />

  <circle cx="15" cy="50%" r="4" style="fill:pink; filter:url(#shadow2);" />

  <circle cx="25" cy="50%" r="4" style="fill:pink; filter:url(#shadow3);" />
</svg>
