<set>

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The <set> SVG element provides a method of setting the value of an attribute for a specified duration.

It supports all attribute types, including those that cannot reasonably be interpolated, such as string and boolean values. For attributes that can be reasonably be interpolated, the <animate> is usually preferred.

Note: The <set> element is non-additive. The additive and accumulate attributes are not allowed, and will be ignored if specified.
