from

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The from attribute indicates the initial value of the attribute that will be modified during the animation.

When used with the to attribute, the animation will change the modified attribute from the from value to the to value. When used with the by attribute, the animation will change the attribute relatively from the from value by the value specified in by.

You can use this attribute with the following SVG elements:

Example

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

html

<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <rect x="10" y="10" height="100">
    <animate attributeName="width" fill="freeze" from="100" to="150" dur="3s" />
  </rect>
</svg>
