CSS scroll-margin-bottom Property

The scroll-margin-bottom property is used to set all the scroll margins to the bottom of an element at once. The value specified for the scroll-margin-bottom determines how much of the page that is primarily outside the support should remain visible.

Hence, the scroll-margin-bottom values represent outsets that define the scroll snap area that is used for snapping this box to the snap port. 

Syntax:

scroll-margin-bottom: length

/* Or */

scroll-margin-bottom: Global_Values

Property values: This property accepts two-properties mentioned above and described below:

  • length: This property refers to the values defined with length units: px, rem, em, vh, etc.
  • Global_Values: This property refers to the global values like initial, inherit, unset, etc.

 Note: scroll-margin-bottom doesn’t accept percentage value as the length. 



Example: In this example, you can see the effect of scroll-margin-bottom by scrolling to a point partway between two of the “interfaces” of the example’s content.
