The scroll-padding property in CSS is part of the CSS Scroll Snap module, designed to enhance the scrolling experience by adding padding inside the scroll container. This property ensures that the content does not touch the edges of the container when scrolled into view, providing a better visual appearance and improving readability.
Using scroll-padding, you can specify padding on all sides of the scroll container or individually set padding for the top, right, bottom, and left sides. This padding helps maintain consistent spacing, making it especially useful in creating user-friendly interfaces with smooth and predictable scrolling behavior.
Basic Setup
To illustrate the scroll-padding property, we will set up a basic HTML structure with internal CSS. This setup will help demonstrate how this property affects the layout and scrolling behavior of elements.

<title>CSS Scroll Padding Example</title>
<style>
html {
scroll-behavior: smooth;
}
body {
font-family: Arial, sans-serif;
display: flex;
overflow-x: scroll;
scroll-snap-type: x mandatory;
}
.section {
min-width: 100vw;
display: flex;
justify-content: center;
align-items: center;
border: 1px solid #ccc;
scroll-snap-align: start;
}
nav {
position: fixed;
top: 10px;
left: 10px;
background-color: rgba(255, 255, 255, 0.8);
padding: 10px;
border-radius: 5px;
}
nav a {
display: block;
margin-bottom: 5px;
color: blue;
text-decoration: none;
}
</style>
</head>
<body>
<nav>
<a href="#section1">Section 1</a>
<a href="#section2">Section 2</a>
<a href="#section3">Section 3</a>
</nav>
<div id="section1" class="section">Section 1</div>
<div id="section2" class="section">Section 2</div>
<div id="section3" class="section">Section 3</div>
</body>
</html>In this setup, we have a navigation menu with links to different sections. The html element uses scroll-behavior: smooth; for smooth scrolling, and the body element applies scroll-snap-type: x mandatory; to enable horizontal scroll snapping. Each section spans the full viewport width, ensuring proper alignment when scrolled into view.
Understanding the scroll-padding Property
The scroll-padding property allows you to set padding on the scroll container, ensuring that content within the container maintains a specified distance from the container’s edges when scrolled into view. This padding can be set for all sides using scroll-padding or individually using scroll-padding-top, scroll-padding-right, scroll-padding-bottom, and scroll-padding-left.
The syntax for the scroll-padding property is straightforward. You can specify a length value (such as pixels, ems, or percentages) to define the padding.
Practical Examples of scroll-padding
Let’s explore practical examples of using the scroll-padding property with different values.
Example: Setting scroll-padding for All Sides
In this example, we will set a scroll-padding for all sides of the scroll container.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>CSS Scroll Padding Example</title>
<style>
html {
scroll-behavior: smooth;
}
body {
font-family: Arial, sans-serif;
display: flex;
overflow-x: scroll;
scroll-snap-type: x mandatory;
scroll-padding: 20px;
}
.section {
min-width: 100vw;
display: flex;
justify-content: center;
align-items: center;
border: 1px solid #ccc;
scroll-snap-align: start;
}
nav {
position: fixed;
top: 10px;
left: 10px;
background-color: rgba(255, 255, 255, 0.8);
padding: 10px;
border-radius: 5px;
}
nav a {
display: block;
margin-bottom: 5px;
color: blue;
text-decoration: none;
}
</style>
</head>
<body>
<nav>
<a href="#section1">Section 1</a>
<a href="#section2">Section 2</a>
<a href="#section3">Section 3</a>
</nav>
<div id="section1" class="section">Section 1</div>
<div id="section2" class="section">Section 2</div>
<div id="section3" class="section">Section 3</div>
</body>
</html>In this example, the body selector sets the scroll-padding property to 20px. This adds 20 pixels of padding on all sides of the scroll container, ensuring that the sections maintain a 20-pixel distance from the viewport edges when scrolled into position. This padding helps create a more visually appealing layout with proper spacing.
Example: Setting Individual scroll-padding Properties
In this example, we will set individual scroll-padding properties for the top, right, bottom, and left sides of the scroll container.

<div id="section2" class="section">Section 2</div>
<div id="section3" class="section">Section 3</div>
</body>
</html>In this example, the body selector sets individual scroll-padding properties for each side. The scroll-padding-top and scroll-padding-bottom are set to 10px, while the scroll-padding-right and scroll-padding-left are set to 30px. This configuration ensures that the sections maintain different distances from the viewport edges, providing customized spacing that enhances the visual layout.
Combining scroll-padding with Other CSS Properties
The scroll-padding property can be combined with other CSS properties to create more advanced scrolling effects and improve the overall layout. Let’s see an example where we combine scroll-padding with scroll-margin to enhance the scrolling experience.

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>CSS Scroll Padding and Margin Example</title>
<style>
html {

}
body {
font-family: Arial, sans-serif;
display: flex;
overflow-x: scroll;
scroll-snap-type: x mandatory;
scroll-padding: 20px;
}
.section {
min-width: 100vw;
display: flex;
justify-content: center;
align-items: center;
border: 1px solid #ccc;
scroll-snap-align: start;
scroll-margin: 10px;
}
nav {
position: fixed;
top: 10px;
left: 10px;
background-color: rgba(255, 255, 255, 0.8);
padding: 10px;
border-radius: 5px;
}
nav a {
display: block;
margin-bottom: 5px;
color: blue;
text-decoration: none;
}
</style>
</head>
<body>
<nav>
<a href="#section1">Section 1</a>
<a href="#section2">Section 2</a>
<a href="#section3">Section 3</a>
</nav>
<div id="section1" class="section">Section 1</div>
<div id="section2" class="section">Section 2</div>
<div id="section3" class="section">Section 3</div>
</body>
</html>In this example, we combine scroll-padding and scroll-margin to enhance the layout. The body selector sets scroll-padding: 20px, providing 20 pixels of padding around the scroll container. Each section has a scroll-margin of 10px, adding additional space around each section. This combination creates a balanced and visually appealing scrolling experience, ensuring that sections do not touch the edges of the viewport and have sufficient spacing.
Conclusion
The scroll-padding property is a valuable tool in the CSS Scroll Snap module, allowing developers to control the padding inside the scroll container. By using this property, you can create smooth and visually appealing scrolling experiences with appropriate spacing.
In this article, we explored the scroll-padding property, starting with a basic setup and moving through practical examples. We demonstrated how to set different values for the property and how to combine it with other CSS properties to enhance the scrolling experience. Understanding and utilizing the scroll-padding property allows for the creation of user-friendly scrolling interfaces that provide a better overall experience for users.
