Question

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.

Notation

Spacing utilities that apply to all breakpoints, from


  Centered element

0 to


  Centered element

1, have no breakpoint abbreviation in them. This is because those classes are applied from


  Centered element

2 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


  Centered element

3 for


  Centered element

0 and


  Centered element

5 for


  Centered element

6,


  Centered element

7,


  Centered element

8,


  Centered element

7 - (by default) for classes that set the margin or padding to margin0

margin1 - (by default) for classes that set the margin or padding to margin4
margin5 - (by default) for classes that set the margin or padding to margin8
margin9 - (by default) for classes that set the margin or padding to padding2
padding3 - for classes that set the margin to auto

(You can add more sizes by adding entries to the padding5 Sass map variable.)

Examples

Here are some representative examples of these classes:

.mt-0 {
  margin-top: 0 !important;
}

.ms-1 {
  margin-left: ($spacer * .25) !important;
}

.px-2 {
  padding-left: ($spacer * .5) !important;
  padding-right: ($spacer * .5) !important;
}

.p-3 {
  padding: $spacer !important;
}

Horizontal centering

Additionally, Bootstrap also includes an padding6 class for horizontally centering fixed-width block level content—that is, content that has padding7 and a padding8 set—by setting the horizontal margins to padding3.


  Centered element

Negative margin

In CSS, margin properties can utilize negative values (padding cannot). These negative margins are disabled by default, but can be enabled in Sass by setting .25rem2.

The syntax is nearly the same as the default, positive margin utilities, but with the addition of .25rem3 before the requested size. Here’s an example class that’s the opposite of .25rem4:

.mt-n1 {
  margin-top: -0.25rem !important;
}

Gap

When using .25rem5, you can make use of .25rem6 utilities on the parent grid container. This can save on having to add margin utilities to individual grid items (children of a .25rem5 container). Gap utilities are responsive by default, and are generated via our utilities API, based on the padding5 Sass map.


  
Grid item 1
  Grid item 2
  Grid item 3

Support includes responsive options for all of Bootstrap’s grid breakpoints, as well as six sizes from the padding5 map (

$spacer: 1rem;
$spacers: (
  0: 0,
  1: $spacer * .25,
  2: $spacer * .5,
  3: $spacer,
  4: $spacer * 1.5,
  5: $spacer * 3,
);

$negative-spacers: if($enable-negative-margins, negativify-map($spacers), null);

9–margin9). There is no 3rem2 utility class as it’s effectively the same as 3rem3.
