Reduce unnecessary forced breaks
break-before and break-after force a page break or column break. However, ‘axf:break-distance’ reduces unnecessary breaks by disabling ‘break-before’ and ‘break-after’ if there is sufficient space on the page. ‘axf:break-distance’ is specified as either a length or a percentage of the height of the containing block.
A page break or column break specified by ‘break-before’ or ‘break-after’ is enabled only when the height of the remaining area is less than the ‘axf:break-distance’ height. If the height of the remaining area is greater than the height specified by ‘axf:break-distance’, no page breaks or column breaks are made. ‘axf: break-distance’ is available in Antenna House Formatter V7.3 and later.
In the next page, break-before: column; is specified on blocks in a two-column page. If only break-before: column; is specified, the column breaks there. However, if ‘axf:break-distance’ is also specified, the height of the column will determine whether or not to break the column.
There are two columns here.
The block has break-before: column, which normally forces a column break. This caused the large space in the previous column.
The following three blocks are identical.
This block has -ah-break-distance: 30%;. A forced break occurs only if the height of the remaining area is less than the -ah-break-distance value.
This block has break-before: column; and -ah-break-distance: 30%; A forced break occurs only if the height of the remaining area is less than the -ah-break-distance value.
