W3C CSS2 Cascading Style Sheets, level 2 - instructional media + ...

Transferring one (large) page box to N x M sheets (called "tiling").
Creating signatures. A signature is a group of pages printed on a sheet,
which, when folded and trimmed like a book, appear in their proper
sequence.
Printing one document to several output trays.
Outputting to a file.
Although CSS2 does not specify how user agents transfer page boxes to
sheets, it does include certain mechanisms for telling user agents about the
target sheet size and orientation [p. 177] .
13.2 Page boxes: the @page rule
The page box is a rectangular region that contains two areas:
The page area. The page area includes the boxes laid out on that page. The
edges of the page area act as the initial containing block [p. 96] for layout
that occurs between page breaks.
The margin area, which surrounds the page area.
Note. In CSS2, the border properties [p. 88] and padding properties [p. 87] do
not apply to pages; they may in the future.
Authors specify the dimensions, orientation, margins, etc. of a page box within
an @page rule. An @page rule consists of the keyword "@page", a page selector
(followed with no intervening space by an optional page pseudo-class), and a
block of declarations (said to be in the page context).
The page selector specifies for which pages the declarations apply. In CSS2,
page selectors may designate the first page, all left pages, all right pages, or a
page with a specific name.
The dimensions of the page box are set with the ’size’ property. The dimensions
of the page area are the dimensions of the page box minus the margin
area.
Example(s):
For example, the following @page rule sets the page box size to 8.5 x 11
inches and creates ’2cm’ margin on all sides between the page box edge and the
page area:
@page { size 8.5in 11in; margin: 2cm }
The ’marks’ property in an @page rule specifies crop and cross marks for the
page box.
13.2.1 Page margins
The margin properties [p. 85] (’margin-top’, ’margin-right’, ’margin-bottom’,
’margin-left’, and ’margin’) apply within the page context [p. 176] . The following
diagram shows the relationships between the sheet, page box, and page
margins:
