scroll-padding-bottom

The scroll-padding-bottom property defines offsets for the bottom of 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.

Values: <length-percentage> An inwards offset from the bottom 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.

Syntax example: scroll-padding-bottom: auto;
