🙋 Introduction

The scroll-padding-block property in CSS is a shorthand property that sets the scroll padding of an element in the block dimension.

This property is used to define the space between the snap position and the edges of the scroll container in the block axis (top and bottom in a vertical writing mode, left and right in a horizontal writing mode). It is part of the CSS Scroll Snap module and helps to create a better scroll snapping experience.

💡 Syntax

The syntax for the scroll-padding-block property is straightforward. It can accept one or two values.

Syntax

Copied

element {
  scroll-padding-block:  | ;
}

If one value is specified, it applies the same padding to both the start and end.
If two values are specified, the first value applies to the start, and the second value applies to the end.

🎛️ Default Value

The default value for the scroll-padding-block property is auto, which means that no extra padding is applied.

🏠 Property Values

Value	Description
length	Defines a fixed amount of padding using units like px, em, rem, etc.
percentage	Defines padding as a percentage of the containing block's size.
auto	The browser automatically calculates the padding.

📄 Example

In this example, we'll apply scroll padding to a container to ensure that items snap with some padding from the top and bottom edges.
