CSS scroll-margin-block property

Last Updated : 24 Jul, 2024

The scroll-margin-block property is used to set all the scroll margins to the start and end of a scroll element at once. This property is shorthand for the scroll-margin-block-start and scroll-margin-block-end property.

The selection of the start and end sides depends upon the writing mode. The start side and end side are top and bottom sides respectively for horizontal-tb writing mode.

Where horizontal-tb stands for horizontal top-to -bottom.

The start side and end side are left and right sides respectively for vertical-rl or vertical-lr writing mode.

Where vertical-rl is the vertical right to left and vertical-lr is the vertical left-to-right.

Syntax:

scroll-margin-block: length
/* Or */
scroll-margin-block: Global_Values

Property values: The scroll-margin-block property accepts two properties mentioned above and described below:

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

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

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