cy attribute define the y-axis coordinate of a center point.

You can use this attribute with the following SVG elements:

• <circle>
• <ellipse>
• <radialGradient>

范例

html,body,svg { height:100% }

								

<svg viewBox="0 0 100 300" xmlns="http://www.w3.org/2000/svg">
  <radialGradient cy="25%" id="myGradient">
    <stop offset="0"    stop-color="white" />
    <stop offset="100%" stop-color="black" />
  </radialGradient>
  <circle  cy="50"  cx="50" r="45"/>
  <ellipse cy="150" cx="50" rx="45" ry="25" />
  <rect x="5" y="205" width="90" height="90" fill="url(#myGradient)" />
</svg>

								

circle

For <circle> , cy defines the y-axis coordinate of the center of the shape.

注意： Starting with SVG2, cy 是 Geometry Property meaning this attribute can also be used as a CSS property for circles.

ellipse

For <ellipse> , cy defines the y-axis coordinate of the center of the shape.

注意： Starting with SVG2, cy 是 Geometry Property meaning this attribute can also be used as a CSS property for ellipses.

radialGradient

For <radialGradient> , cy defines the y-axis coordinate of the end circle for the radial gradient.

范例

html,body,svg { height:100% }

								

<svg viewBox="0 0 34 10" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <radialGradient cy="0" id="myGradient000">
      <stop offset="0%"   stop-color="gold" />
      <stop offset="50%"  stop-color="green" />
      <stop offset="100%" stop-color="white" />
    </radialGradient>
    <radialGradient cy="50%" id="myGradient050">
      <stop offset="0%"   stop-color="gold" />
      <stop offset="50%"  stop-color="green" />
      <stop offset="100%" stop-color="white" />
    </radialGradient>
    <radialGradient cy="100%" id="myGradient100">
      <stop offset="0%"   stop-color="gold" />
      <stop offset="50%"  stop-color="green" />
      <stop offset="100%" stop-color="white" />
    </radialGradient>
  </defs>
  <rect x="1"  y="1" width="8" height="8" fill="url(#myGradient000)" stroke="black" />
  <rect x="13" y="1" width="8" height="8" fill="url(#myGradient050)" stroke="black" />
  <rect x="25" y="1" width="8" height="8" fill="url(#myGradient100)" stroke="black" />
</svg>
