is it normal for OPC to be display has on column on responsive template?

When combine with the bootstrap template, OPC is display in several columns.

I am not able to add screenshot somehow but:

OPC on bootstrap is like

column 1 column 2 column 3

billing info cart content other
shipping info comment box


OPC on responsive is one column only

billing info
shipping info
comment
cart content

How can i get the 3 column on responsive classic template?

Thank you
