Spacing can be added to an element with Bootstrap utility classes at any breakpoint. These classes include:
m-{bp}-{1|2|3|4|5}
adds margin
p-{bp}-{1|2|3|4|5}
adds padding
The integers used for sizing correspond to pre-set multiplies of the $spacer
value. You can find more information here. The $spacer
value and multipliers can be changed in the Bootstrap Variables file.
