<feDropShadow>

The SVG <feDropShadow> filter primitive creates a drop shadow of the input image. It can only be used inside a <filter> element.

The drop shadow color and opacity can be changed by using the flood-color and flood-opacity presentation attributes.

<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>
