The scroll-padding-inline property in CSS is part of the CSS Scroll Snap module, designed to improve the scrolling experience by specifying padding along the inline axis (left and right for horizontal writing modes, top and bottom for vertical writing modes) within a scroll container. This property ensures that content maintains a consistent distance from the container’s inline edges when scrolled into view, enhancing the visual layout and readability of the content.
Using scroll-padding-inline, you can define padding for the inline axis of the scroll container. This padding helps ensure that content does not touch the container’s inline edges, providing a more aesthetically pleasing and readable layout. In this article, we will explore the scroll-padding-inline property in detail, understand its application, and see practical examples to illustrate its usage.
Basic Setup
To illustrate the scroll-padding-inline 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 Inline Example</title>
<style>
html {
scroll-behavior: smooth;
}
body {
font-family: Arial, sans-serif;
display: flex;
flex-direction: row;
overflow-x: scroll;
scroll-snap-type: x mandatory;
}
.section {
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-inline Property
The scroll-padding-inline property allows you to set padding along the inline axis (left and right for horizontal writing modes, top and bottom for vertical writing modes) of the scroll container. This padding ensures that the content maintains a specified distance from the container’s inline edges when scrolled into view.
The syntax for the scroll-padding-inline property is straightforward. You can specify a length value (such as pixels, ems, or percentages) to define the padding. This property is particularly useful in ensuring that content does not touch the container’s inline edges, providing a more visually appealing and readable layout.
Practical Examples of scroll-padding-inline
Let’s explore practical examples of using the scroll-padding-inline property with different values.
Example: Setting scroll-padding-inline for All Sections
In this example, we will set a scroll-padding-inline for all sections in the scroll container.

<style>
html {
scroll-behavior: smooth;
}
body {
font-family: Arial, sans-serif;
display: flex;
flex-direction: row;
overflow-x: scroll;
scroll-snap-type: x mandatory;
scroll-padding-inline: 20px;
}
.section {
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-inline property to 20px. This adds 20 pixels of padding to the inline axis of the scroll container, ensuring that the sections maintain a 20-pixel distance from the viewport’s left and right edges when scrolled into position. This padding helps create a more visually appealing layout with proper spacing.
Combining scroll-padding-inline with Other CSS Properties
The scroll-padding-inline 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-inline with scroll-margin to enhance the scrolling experience.

overflow-x: scroll;
scroll-snap-type: x mandatory;
scroll-padding-inline: 20px;
}
.section {

scroll-snap-align: start;
scroll-margin: 15px;

<a href="#section1">Section 1</a>
<a href="#section2">Section 2</a>
<a href="#section3">Section 3</a>

<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-inline set to 20px with scroll-margin set to 15px for each section. This combination ensures that sections maintain a 20-pixel distance from the viewport’s left and right edges and an additional 15-pixel margin around each section, resulting in a balanced and visually pleasing layout.
Conclusion
The scroll-padding-inline property is a valuable tool in the CSS Scroll Snap module, enabling developers to specify padding along the inline axis in a scroll container. This property enhances the scrolling experience by maintaining consistent spacing and improving readability.
In this article, we explored the scroll-padding-inline 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 create a more visually appealing layout.
