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

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

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.
