<?blockcolgut>
Description
Specifies the width of a column gutter as a fixed width, a relative width or a combination of both.
Syntax
<?blockcolgut @:? +:? value:n ( +:? value:n )*>
@
(optional) Used when pre-specifying column gutters at the top of the block. It specifies that this column is the one whose properties should be repeated if required, for any columns whose gutter has not been actually specified.
+
(optional) Allows the column gutters to be specified in separate <?blockcolgut> commands rather than together in one with multiple values.
value
width
Fixed width: change the width of the block to make it fit an exact measurement, e.g. <?blockcolgut=120mm>. Defaults to mm if no units are specified with the measurement.
rel*
A relative width
Additional Information
When creating a new block, no column gutter is permitted after the right hand column as a default. To apply a gutter here use the <?blockgutr> command.
The <?blockskipegut> command can override this. Note that a gutter will only appear after the right hand column if the gutter was specified explicitly (i.e. not implied by apply a repeat to existing <?blockcolgut> specifications), even if <?blockskipegut> is in place.
