Print Media
The printed page, while having many similarities to the screen, differs in
many ways as well, most notably that the contents of a document are
split across multiple fixed-sized pages rather than one single continuous
viewport. The properties listed in this section help control the presenta-

page breaks occur within the document's content.
page-break-before and page-break-after

or after a given piece of content, which is most useful when applied to
articles, headers, tables, or other “blocks” of content.
■ auto : The user-agent determines the most appropriate places for
a page break (default).
■ always : This tells the user agent to always break before (or after)
the selected element.
■ avoid : This tells the user agent to attempt to avoid breaks before
