Assign responsive-friendly margin
or padding
values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from .25rem
to 3rem
.
We have further added quick margin and padding options for by using gutter space variable .m-g
, margin bottom gutter .mb-g
. Padding gutter can be adding by using .p-g
modifier. The *-g
will change based on the gutter variable.
Spacing utilities that apply to all breakpoints, from xs
to xl
, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0
and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.
The classes are named using the format {property}{sides}-{size}
for xs
and {property}{sides}-{breakpoint}-{size}
for sm
, md
, lg
, and xl
.
Where property is one of:
t
- for classes that set margin-top
or padding-top
b
- for classes that set margin-bottom
or padding-bottom
l
- for classes that set margin-left
or padding-left
r
- for classes that set margin-right
or padding-right
x
- for classes that set both *-left
and *-right
y
- for classes that set both *-top
and *-bottom
margin
or padding
on all 4 sides of the elementWhere size is one of:
0
- for classes that eliminate the margin
or padding
by setting it to 0

- (by default) for classes that set the margin
or padding
to $spacer * .25
2
- (by default) for classes that set the margin

Additionally, Bootstrap also includes an .mx-auto
class for horizontally centering fixed-width block level content—that is, content that has display: block
and a width
set—by setting the horizontal margins to auto
.
n
before the requested size.
Here’s an example of customizing the Bootstrap grid at the medium (md
) breakpoint and above. We’ve increased the .col
padding with .px-md-5
and then counteracted that with .mx-md-n5
on the parent .row
.
