scroll-behavior

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

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.

Values: This property is specified as one of the following keyword values:

Values: auto The scrolling box scrolls instantly. smooth The scrolling box scrolls in a smooth fashion using a user-agent-defined easing function over a user-agent-defined period of time. User agents should follow platform conventions, if any.
