scroll-behavior

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2022.

The scroll-behavior CSS property sets the behavior for a scrolling box when scrolling is triggered by the navigation or CSSOM scrolling APIs.

Try it

Note that any other scrolls, such as those performed by the user, are not affected by this property. When this property is specified on the root element, it applies to the viewport instead. This property specified on the body element will not propagate to the viewport.

User agents are allowed to ignore this property.
