Definition and Usage
The scroll-margin-top property specifies
the distance between the snap position and the container.
Snap position is the position on the child element where it snaps into place in the container when you stop scrolling. Snap position is set with scroll-snap-align property, but can also be affected by CSS properties direction and writing-mode.
Note: This property only works if the snap position is placed at the top of the child element.
To see the effect from the scroll-margin-top property, the scroll-margin-top and scroll-snap-align properties must be set on the child elements, and the scroll-snap-type property must be set on the parent element.

More Examples
Image gallery
The scroll-margin-top property can be used in an image gallery with snap behaviour. Here, the scroll-margin-top lets the user see that there is an image at the top. Scroll past the first image to see the effect:
#container > img {
scroll-margin-top: 30px;
}
Snap position
The snap position must be placed on top of the child elements for the scroll-margin-top property to work. In this example the writing-mode property changes the snap position from top to right side of child elements. With the code like this the scroll-margin-top property no longer works:
#container {
writing-mode: vertical-rl;
}
#container > div {
scroll-margin-top: 30px;
scroll-snap-align: start none;
}
