SVG Gradients - Radial

The <radialGradient> element is used to define a radial gradient

SVG Radial Gradient - <radialGradient>

The <radialGradient> element is used to define a radial gradient.

The <radialGradient> element must be nested within a <defs> tag. The <defs> tag is short for definitions and contains definition of special elements (such as gradients).

Example 1

Define an ellipse with a radial gradient from white to blue:

Sorry, your browser does not support inline SVG.

Here is the SVG code:

Example

<svg height="150" width="500">
  <defs>
    <radialGradient id="grad1" cx="50%" cy="50%" r="50%" fx="50%" fy="50%">
      <stop offset="0%" style="stop-color:rgb(255,255,255);
      stop-opacity:0" />
      <stop offset="100%" style="stop-color:rgb(0,0,255);stop-opacity:1" />
    </radialGradient>
  </defs>
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />
</svg>
Code explanation:
  • The id attribute of the <radialGradient> tag defines a unique name for the gradient
  • The cx, cy and r attributes define the outermost circle and the fx and fy define the innermost circle
  • The color range for a gradient can be composed of two or more colors. Each color is specified with a <stop> tag. The offset attribute is used to define where the gradient color begin and end
  • The fill attribute links the ellipse element to the gradient

    • Example 2

    Define another ellipse with a radial gradient from white to blue:

    Sorry, your browser does not support inline SVG.

    Here is the SVG code:

    Example

    <svg height="150" width="500">
      <defs>
        <radialGradient id="grad2" cx="20%" cy="30%" r="30%" fx="50%" fy="50%">
          <stop offset="0%" style="stop-color:rgb(255,255,255);
          stop-opacity:0" />
          <stop offset="100%" style="stop-color:rgb(0,0,255);stop-opacity:1" />
        </radialGradient>
      </defs>
      <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad2)" />
    </svg>
