Managing Headers, Footers & Page Breaks in PDFs
Page breaks can be confusing.
The page-break-after CSS rule will always work if applied correctly. However, this rule will not work if your style sheet changes a div from display:block. Ensure that the page-break-after rule is applied to a block-level element, preferably a div that is a direct child of the body tag.
The HTML example below demonstrates
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Print Page Breaks with Header and Footer</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
}
header, footer {
position: fixed;
width: 100%;
text-align: center;
background-color: #f1f1f1;
padding: 10px 0;
}
header {
top: 0;
}
footer {
bottom: 0;
}
.content {
margin: 150px 20px; /* Adjust margins to prevent content overlap with header and footer */
}
.page-break {
page-break-after: always;
display: block; /* Ensure it remains a block-level element */
}
</style>
</head>
<body>
<header>
<h1>Document Title</h1>
<p>Header Content</p>
</header>
<footer>
<p>Footer Content</p>
</footer>
<div class="content">

<p>This is the first section. After this section, there will be a page break.</p>
</div>
<div class="content">
<div class="page-break">
<h2>Section 2</h2>
<p>This is the second section. The header and footer continue to be displayed, and the content starts on a new page.</p>
</div>
