KEY
TYPE
VALUE
StartIndent
number
(Optional; inheritable)
The distance from the start edge of the reference area
to that of the BLSE, measured in default user space units in the inline-pro-
gression direction. This attribute applies only to structure elements with a
Placement
attribute of
Block
or
Start
(see “General Layout Attributes” on page
Placement
values.
Default value: 0.
Note:
A negative value for this attribute places the start edge of the BLSE out-
side that of the reference area. The results are implementation-dependent and
may not be supported by all Tagged PDF consumer applications or export
formats.
Note:
If a structure element with a
StartIndent
attribute is placed adjacent to a
floating element with a
Placement
attribute of
Start
, the actual value used for
the element’s starting indent is its own
StartIndent
attribute or the inline extent
of the adjacent floating element, whichever is greater. This value may be further
adjusted by the element’s
TextIndent
attribute, if any.
EndIndent
number
(Optional; inheritable)
The distance from the end edge of the BLSE to that of
the reference area, measured in default user space units in the inline-progres-
sion direction. This attribute applies only to structure elements with a
Placement
attribute of
Block
or
End
(see “General Layout Attributes” on page
Placement
values.
Default value: 0.
Note:
A negative value for this attribute places the end edge of the BLSE outside
that of the reference area. The results are implementation-dependent and may
not be supported by all Tagged PDF consumer applications or export formats.
Note:
If a structure element with an
EndIndent
attribute is placed adjacent to a
floating element with a
Placement
attribute of
End
, the actual value used for the
element’s ending indent is its own
EndIndent
attribute or the inline extent of the
adjacent floating element, whichever is greater.
TextIndent
number
(Optional; inheritable; applies only to some BLSEs, as described below)
The ad-
ditional distance, measured in default user space units in the inline-progres-
sion direction, from the start edge of the BLSE, as specified by
StartIndent
(above), to that of the first line of text. A negative value indicates a hanging
indent. Default value: 0.
This attribute applies only to paragraphlike BLSEs and those of structure
types
Lbl
(Label),
LBody
(List body),
TH
(Table header), and
TD
(Table data),
provided that they contain content other than nested BLSEs.
