Computed value:

Description:
Defines whether one or more page breaks should be placed before an element. Although it is
theoretically possible to force breaks with always , it is not possible to guarantee prevention;
avoid asks the user agent to avoid inserting a page break if possible. The keyword left is
used to insert enough breaks before the element to make the page be a left-hand page; simil-
arly, right is used for a right-hand page.
This property is essentially replaced by break-before , but browser support for page-break-
before may be stronger.
Examples:
section {page-break-before: always;}
h2 {page-break-before: avoid;}
