ThekeyPoints attribute indicates the simple duration of an animation.

You can use this attribute with the following SVG elements:

• <animate>
• <animateMotion>
• <animateTransform>
• <set>

Example

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

<svg  viewBox="0 0 120 120"  xmlns="http://www.w3.org/2000/svg"  xmlns:xlink="http://www.w3.org/1999/xlink">  <path    d="M10,110 A120,120 -45 0,1 110 10 A120,120 -45 0,1 10,110"    stroke="lightgrey"    stroke-width="2"    fill="none"    />  <circle cx="10" cy="110" r="3" fill="lightgrey" />  <circle cx="110" cy="10" r="3" fill="lightgrey" />  <circle r="5" fill="red">    <animateMotion      dur="3s"      repeatCount="indefinite"      keyPoints="0;0.5;1"      keyTimes="0;0.15;1"      calcMode="linear">      <mpath href="#motionPath" />    </animateMotion>  </circle></svg>

Usage notes

<number> [; <number>] ;?

This value defines a semicolon-separated list of floating point values between 0 and 1 and indicates how far along the motion path the object shall move at the moment in time specified by correspondingkeyTimes value. The distance is calculated along the path specified by thepath attribute. Each progress value in the list corresponds to a value in thekeyTimes attribute list.

If a list of key points is specified, there must be exactly as many values in thekeyPoints list as in thekeyTimes list.

If there's a semicolon at the end of the value, optionally followed by white space, both the semicolon and the trailing white space are ignored.

If there are any errors in the value specification (i.e., bad values, too many or too few values), then that's an error.
