Abstract

This module describes the fragmentation model that partitions a flow into pages. It builds on the Page model module and introduces and defines the fragmentation model. It adds functionality for pagination, breaking variable fragment size and orientation, widows and orphans.

2. Fragmentation Model and Terminology

3. Controlling Breaks

3.1. Forced breaks and keep-together: the ‘break-before’, ‘break-after’, ‘break-inside’ properties

break-before

CSS	auto | always | left | right | page | column | region | avoid | avoid-page | avoid-column | avoid-region | inherit
XSL break-before	auto | column | page | even-page | odd-page | inherit
XSL 1.1 keep-with-previous	<keep> | inherit

break-after

CSS	auto | always | left | right | page | column | region | avoid | avoid-page | avoid-column | avoid-region | inherit
XSL 1.1	auto | column | page | even-page | odd-page | inherit
XSL 1.1 keep-with-next	<keep> | inherit

break-before/-after Comparison

CSS	XSL 1.1	Discussion
auto	auto
always	-
left	odd-page or even-page	Depends on writing mode and initial page number
right	even-page	Depends on writing mode and initial page number
page	page
column	column
region	-	Proposed for XSL-FO 2.0
avoid	keep-with-previous/next="always"
avoid-page	keep-with-previous/next.within-page="always"
avoid-column	keep-with-previous/next.within-column="always"
avoid-region	-	keep-with-previous/next.within-region proposed for XSL-FO 2.0

break-inside

CSS	avoid | avoid-page | avoid-column | avoid-region
XSL 1.1 "keep-together"	<keep> | inherit

break-inside Comparison

CSS3 does not support integer keep strengths.

CSS	XSL 1.1	Discussion
auto	auto
avoid	keep-together="always"
avoid-page	keep-together.within-page="always"
avoid-column	keep-together.within-column="always"
avoid-region	-	keep-together.within-region proposed for XSL-FO 2.0
