float Which side the template floats to. Default to "right" but can be "left" or "center".
style Additional CSS syntax which defines the style of the whole box.

map BS row templates which comprise the diagram.
mapn n represents numbers 2 to 10. Additional map space. By separating maps into different map parameters, the column alignment of the maps will not affect each other. This is useful if you are displaying two maps where one uses the ordinary BSn row templates (single-side text columns) and the other one uses BSn-2 (dual-side text columns), as the different row templates are not compatible with each other.
