Table 344 · Additional standard layout attributes specific to block-level structure elements (continued)
ISO 32000-1:2008, §14.8.5.4.3 · PDF page 608 ↗
/SpaceBefore number
(Optional; not inheritable) The amount of extra space preceding the before edge of the BLSE, measured in default user space units in the block-progression direction. This value shall be added to any adjustments induced by the LineHeight attributes of ILSEs within the first line of the BLSE (see “Layout Attributes for ILSEs” in 14.8.5.4, “Layout Attributes”). If the preceding BLSE has a SpaceAfter attribute, the greater of the two attribute values shall be used. Default value: 0. This attribute shall be disregarded for the first BLSE placed in a given reference area.
Qualifier: Optional; not inheritable
