CSS page-break-after Property: Controlling Page Breaks After Elements
The CSS page-break-after property is used to define how a page break should behave after a specified element when printing a web page. This property is essential for controlling the layout of printed documents, ensuring content is logically separated and presented in a readable format. It’s particularly useful for preventing headings or important sections from being split across pages.
Understanding the page-break-after Property
The page-break-after property allows you to specify whether a page break should occur after an element. By default, browsers handle page breaks automatically, but this property gives you the control to enforce or avoid breaks where necessary. This is especially useful for ensuring that titles, sections, and other key elements are not awkwardly split across pages.
Syntax
The page-break-after property can be set with various values, each influencing the page break behavior:
selector {
page-break-after: auto | always | avoid | left | right | recto | verso |
initial | inherit;
}
Values
The following table describes the possible values for the page-break-after property:
| Value | Description |
|---|---|
| `auto` | The browser determines if a page break is necessary after the element. This is the default behavior. |
| `always` | Always insert a page break after the element. |
| `avoid` | Avoid a page break after the element, if possible. |
| `left` | Insert one or two page breaks after the element so that the next page is formatted as a left page. |
| `right` | Insert one or two page breaks after the element so that the next page is formatted as a right page. |
| `recto` | Behaves like `right`: insert one or two page breaks after the element so that the next page is formatted as a right page. |
| `verso` | Behaves like `left`: insert one or two page breaks after the element so that the next page is formatted as a left page. |
| `initial` | Sets the property to its default value (`auto`). |
| `inherit` | Inherits this property from its parent element. |
Examples
Let’s explore several practical examples that demonstrate how to use the page-break-after property effectively.
Example 1: Forcing a Page Break After a Heading
In this example, we’ll ensure that a page break always occurs after each <h2> heading, effectively starting each new section on a new page.
<!DOCTYPE html>
<html>
<head>
<title>Page Break After Example 1</title>
<style>
@media print {
h2 {
page-break-after: always;
}
}
</style>
</head>
<body>
<h2>Section 1</h2>
<p>Content for section 1.</p>
<h2>Section 2</h2>
<p>Content for section 2.</p>
<h2>Section 3</h2>
<p>Content for section 3.</p>
</body>
</html>
In print preview, each <h2> heading and its subsequent content will appear on a new page.
Example 2: Avoiding Page Breaks After Images
Here, we’ll prevent page breaks from occurring immediately after images to avoid awkward layouts where an image is left alone at the bottom of a page.
<!DOCTYPE html>
<html>
<head>
<title>Page Break After Example 2</title>
<style>
@media print {
img {
page-break-after: avoid;
}
}
</style>
</head>
<body>
<p>
This is some text before the image.
<img
src="https://via.placeholder.com/300x150"
alt="Placeholder Image"
/>
This is some text after the image.
</p>
</body>
</html>
The browser will attempt to keep the image and surrounding text together on the same page.
Example 3: Using left and right for Book Layout
This example demonstrates how to use page-break-after with left and right values to format content for a book layout, ensuring chapters start on the right-hand side (recto) of a spread.
<!DOCTYPE html>
<html>
<head>
<title>Page Break After Example 3</title>
<style>
@media print {
h1 {
page-break-after: right;
}
}
</style>
</head>
<body>
<h1>Chapter 1</h1>
<p>Content for chapter 1.</p>
<h1>Chapter 2</h1>
<p>Content for chapter 2.</p>
</body>
</html>
Each <h1> heading will start on a right-hand page, with blank pages inserted as needed.
Example 4: Inheriting Page Break Behavior
In this example, we’ll set the page break behavior on a parent element and have its child elements inherit that behavior.
<!DOCTYPE html>
<html>
<head>
<title>Page Break After Example 4</title>
<style>
@media print {
.section {
page-break-after: avoid;
}
}
</style>
</head>
<body>
<div class="section">
<h2>Section Title</h2>
<p>Content within the section.</p>
</div>
</body>
</html>
The .section div and its contents will attempt to stay together on the same page.
Example 5: Using initial to Reset Page Break Behavior
This example shows how to reset any previously set page-break-after property to its default value (auto).
<!DOCTYPE html>
<html>
<head>
<title>Page Break After Example 5</title>
<style>
@media print {
h2 {
page-break-after: always;
}
.reset-break {
page-break-after: initial;
}
}
</style>
</head>
<body>
<h2>Section 1</h2>
<p>Content for section 1.</p>
<h2 class="reset-break">Section 2</h2>
<p>Content for section 2.</p>
</body>
</html>
The <h2> heading with the class reset-break will not force a page break after it, reverting to the browser’s default behavior.
Real-World Applications
The page-break-after property is beneficial in several scenarios:
