With the current docs directory setup, I'm making too many mistakes and have to manually address path changes and directory moves on deploy. This makes for a frustrating experience developing locally and shipping releases. With this PR, we're basically back to the same setup from v3—duplicating the dist directory into our docs directory. Not the most ideal, but very straightforward for me as the release manager.

docs | Spacing | Bootstrap includes a wide range of shorthand responsive margin and padding utility classes to modify an element's appearance. | utilities | true |
How it works
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 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:
m
- for classes that setmargin
p
- for classes that setpadding
Where sides is one of:
t
- for classes that setmargin-top
orpadding-top
b
- for classes that setmargin-bottom
orpadding-bottom
l
- for classes that setmargin-left
orpadding-left
r
- for classes that setmargin-right
orpadding-right
x
- for classes that set both*-left
and*-right
y
- for classes that set both*-top
and*-bottom
- blank - for classes that set a
margin
orpadding
on all 4 sides of the element
Where size is one of:
0
- for classes that eliminate themargin
orpadding
by setting it to0
1
- (by default) for classes that set themargin
orpadding
to$spacer * .25
2
- (by default) for classes that set themargin
orpadding
to$spacer * .5
3
- (by default) for classes that set themargin
orpadding
to$spacer
4
- (by default) for classes that set themargin
orpadding
to$spacer * 1.5
5
- (by default) for classes that set themargin
orpadding
to$spacer * 3
auto
- for classes that set themargin
to auto
(You can add more sizes by adding entries to the $spacers
Sass map variable.)
Examples
Here are some representative examples of these classes:
{% highlight scss %} .mt-0 { margin-top: 0 !important; }
.ml-1 { margin-left: ($spacer * .25) !important; }
.px-2 { padding-left: ($spacer * .5) !important; padding-right: ($spacer * .5) !important; }
.p-3 { padding: $spacer !important; } {% endhighlight %}
Horizontal centering
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
.
{% highlight html %}
