Spacing
Front includes a wide range of shorthand responsive margin and padding utility classes to modify an element's appearance.
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.
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 setmarginp- for classes that setpadding
Where sides is one of:

(You can add more sizes by adding entries to the $spacers Sass map variable via: _theme-variables.scss.)
The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Offset spacings
Front includes several offset classes, like:
<div class="ml-n2">.ml-n2</div>
<div class="ml-n3">.ml-n3</div>
<div class="mt-n1">.mt-n1</div>
<div class="mt-n5">.mt-n5</div>
<div class="mt-n6">.mt-n6</div>
<div class="mt-n9">.mt-n9</div>
<div class="mt-n23">.mt-n23</div>
<div class="mb-n9">.mb-n9</div>
Examples
Here are some representative examples of these classes:
.mt-0 {
margin-top: 0 !important;
}
.ml-1 {
margin-left: ($spacer * .25) !important;
}
.px-2 {
left: ($spacer * .5) !important;
padding-right: ($spacer * .5) !important;
}
.p-3 {
padding: $spacer !important;
}
Horizontal centering
Additionally, Front 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.
<div class="mx-auto bg-primary text-white" style="width: 200px;">
Centered element
</div>
