The scroll-padding-inline-end property in CSS is a part of the CSS Scroll Snap module designed to improve user experience by providing control over the padding at the end of the inline axis in a scroll container. This property allows developers to specify a padding area on the inline end side (right side in left-to-right writing modes, left side in right-to-left writing modes), ensuring that content maintains a consistent distance from the container’s inline end edge when scrolled into view.
Using scroll-padding-inline-end helps create visually appealing and user-friendly scrollable layouts by preventing content from touching the container’s inline end edge. This is particularly useful in enhancing readability and providing a balanced layout. In this article, we will explore the scroll-padding-inline-end property in detail, understand its application, and see practical examples to illustrate its usage.
Basic Setup
To demonstrate the scroll-padding-inline-end property, we will set up a basic HTML structure with internal CSS. This setup will help show how this property affects the layout and scrolling behavior of elements.

<title>CSS Scroll Padding Inline End 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-end Property
The scroll-padding-inline-end property allows you to set padding along the inline end axis of the scroll container. This ensures that the content maintains a specified distance from the container’s inline end edge when scrolled into view. The syntax for the scroll-padding-inline-end property is straightforward, allowing you to specify a length value (such as pixels, ems, or percentages) to define the padding.
This property is particularly useful in maintaining a visually appealing and readable layout by ensuring that content does not touch the container’s inline end edge.
Practical Examples of scroll-padding-inline-end
Let’s explore practical examples of using the scroll-padding-inline-end property with different values.
Example: Setting scroll-padding-inline-end for All Sections
In this example, we will set a scroll-padding-inline-end for all sections in the scroll container.
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<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-end: 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-end property to 20px. This adds 20 pixels of padding to the inline end axis of the scroll container, ensuring that the sections maintain a 20-pixel distance from the viewport’s right edge (in a left-to-right writing mode) when scrolled into position. This padding helps create a more visually appealing layout with proper spacing.
Combining scroll-padding-inline-end with Other CSS Properties
The scroll-padding-inline-end 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-end with scroll-margin to enhance the scrolling experience.

.section {

scroll-margin: 15px;
}

<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-end 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 right edge and an additional 15-pixel margin around each section, resulting in a balanced and visually pleasing layout.
