The box-decoration-break property in CSS is used to control how box decorations are applied to fragments of an element. This property is particularly useful when an element is split across multiple lines, pages, or columns, and you want to control whether the box decorations are continuous or start anew for each fragment. By using the box-decoration-break property, designers can ensure consistent and visually appealing decorations for elements, regardless of how they are broken up in the layout.
Controlling box decorations is essential for maintaining design integrity in complex layouts, such as multi-column texts, paginated content, and responsive designs. The box-decoration-break property supports values like slice and clone, allowing for precise control over how decorations are applied. This article will explore the principles of the box-decoration-break property in CSS, provide practical examples, and discuss best practices for its implementation. By the end of this article, you will have a comprehensive understanding of how to control box decorations effectively.
Understanding the Box-Decoration-Break Property in CSS
The box-decoration-break property in CSS specifies how the decorations (borders, padding, backgrounds, etc.) of an element are applied when the element is broken into multiple fragments. It can take values such as slice and clone.

<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.basic-box-decoration-break {

<p>This is a <span class="basic-box-decoration-break">basic example</span> of using the box-decoration-break property in CSS.</p>
</body>
</html>In this example, the .basic-box-decoration-break class sets the box-decoration-break property to slice, which means that the box decorations are applied as if the element were not broken into fragments. This basic usage demonstrates how to use the box-decoration-break property to control box decorations.
Using Box-Decoration-Break with Different Values
The box-decoration-break property can be set using different values, such as slice and clone. These values control whether the box decorations are continuous or restarted for each fragment.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.slice-decoration {
display: inline-block;
padding: 10px;
border: 2px solid red;
background-color: lightcoral;
box-decoration-break: slice;
}
.clone-decoration {
display: inline-block;
padding: 10px;
border: 2px solid green;
background-color: lightgreen;
box-decoration-break: clone;
}
</style>

<p>This is a <span class="clone-decoration">clone example</span> of using the box-decoration-break property.</p>
</body>
</html>In this example, the .slice-decoration and .clone-decoration classes use different values for the box-decoration-break property. The slice value ensures that the box decorations are continuous, while the clone value restarts the decorations for each fragment. This demonstrates how to apply different values to the box-decoration-break property.
Combining Box-Decoration-Break with Other CSS Properties
The box-decoration-break property can be combined with other CSS properties like border, padding, and background to achieve more complex and visually appealing effects.
<!DOCTYPE html>
