How to insert a page break in HTML so wkhtmltopdf parses it?

When I use wkhtmltopdf, I work with the following classes:

.keep-together {
    page-break-inside: avoid;
}

.break-before {
    page-break-before: always;
}

.break-after {
    page-break-after: always;
}

So I can force:

• That a particular container content is not spread over two pages (if it fits one page). When using the keep-together class a page break is created before the container if necessary.
• That a page break is forced before a particular container.
• That a page break is forced after a particular container.

The @media print didn't work for me with wkhtmltopdf.

Specify a CSS rule specific to the print media type. There are a number of properties that can be used for paging. I find it easiest to attach the page-break-before property to a class, as shown below.

In the HTML:

<p>Page 1, paragraph 1</p>
<p class="new-page">Page 2, paragraph 1</p>
<p>Page 2, paragraph 2</p>

In the CSS:

@media print {
  .new-page {
    page-break-before: always;
  }
}
