NAME

Top

PDF::FromHTML::Template::Container::Always

PURPOSE

Top

To require that any child of this node will always render on every page. Normally, a node will not render on a given page if a node before it has triggered a pagebreak. ALWAYS nodes will always render on every page.

Primarily, this is used as a base class for HEADER and FOOTER. However, you might want something to always render on every page outside the header and footer areas. For example, a watermark.
