The scroll-padding properties define offsets for the optimal viewing region of the scrollport: the region used as the target region for placing things in view of the user. This allows the author to exclude regions of the scrollport that are obscured by other content (such as fixed-positioned toolbars or sidebars) or to put more breathing room between a targeted element and the edges of the scrollport.

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

/* Keyword values */
scroll-padding-block: auto;

/* <length> values */
scroll-padding-block: 10px;
scroll-padding-block: 1em 0.5em;
scroll-padding-block: 10%;

/* Global values */
scroll-padding-block: inherit;
scroll-padding-block: initial;
scroll-padding-block: revert;
scroll-padding-block: revert-layer;
scroll-padding-block: unset;

Values

An inwards offset from the corresponding edge of the scrollport, as a valid length or a percentage.

auto

The offset is determined by the user agent. This will generally be 0px, but a user agent is able to detect and do something else if a non-zero value is more appropriate.
