Definition and Usage
The scroll-padding-block property specifies
the distance in block direction, from the container to the snap position on the child elements.
This means that when you stop scrolling, the scrolling will quickly adjust and stop at a specified distance in block direction, between the snap position and the container.
Block direction is where the next line is put compared to the position of an existing line, and this is also how tags with CSS display: block; like <p> and <div> tags are laid out on a page. Block direction is dependent on the written language, i.e. Mongolian where new lines are laid out left to right which makes block direction left to right, while pages in English have a downward block direction. Block direction can be defined with CSS property writing-mode.
Snap position is the position on the child element where it snaps into place in the container when you stop scrolling.
Note: This property only works if the scroll-snap-align property is set to 'start' or 'end' for the block direction.
The scroll-padding-block property is a shorthand property for the following properties:
Values for the scroll-padding-block property can be set in different ways:
If the scroll-padding-block property has two values:
- scroll-padding-block: 10px 50px;
- distance at start is 10px
- distance at end is 50px
If the scroll-padding-block property has one value:
- scroll-padding-block: 10px;
- distance at start and end is 10px
To see the effect from the scroll-padding-block property, the scroll-snap-align property must be set on the child elements, and the scroll-padding-block and the scroll-snap-type properties must be set on the parent element.
The CSS
scroll-padding-block and
scroll-padding-inline properties are very similar to CSS properties
scroll-padding-top,
scroll-padding-bottom,
scroll-padding-left and
scroll-padding-right, but the
scroll-padding-block and
scroll-padding-inline properties are dependent on block and inline directions.

More Examples
Image gallery
The scroll-padding-block property can be used in an image gallery with snap behaviour, to push images below a fixed element:
#container {
scroll-padding-block: 30px 0;
}
Example
With the writing-mode property value of the container element set to vertical-rl, the start of the container and child elements in block direction is moved from top to right side, and the end of the container and child elements is moved from bottom to left side. This affects the scroll snap behaviour, and how the scroll-padding-block property works:
#container {
scroll-padding-block: 20px 0;
writing-mode: vertical-rl;
}
