title: Utility classes
---
Bootstrap includes dozens of utilities—classes with a single purpose. They're designed to keep the number of declarations in your CSS down while allowing for quick and easy development.
Bootstrap includes dozens of utilities—classes with a single purpose. They're designed to reduce the frequency of highly repetitive declarations in your CSS down while allowing for quick and easy development.
## Contents
* Will be replaced with the ToC, excluding the "Contents" header
{:toc}
## Spacing
Assign `margin` or `padding` to an element or a subset of it's sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. All classes are multiples on the global default value, `1rem`.
### Margin
{% highlight scss %}
.m-a-0 { margin: 0; }
.m-t-0 { margin-top: 0; }
.m-r-0 { margin-right: 0; }
.m-b-0 { margin-bottom: 0; }
.m-l-0 { margin-left: 0; }
.m-a { margin: $spacer; }
.m-t { margin-top: $spacer-y; }
.m-r { margin-right: $spacer-x; }
.m-b { margin-bottom: $spacer-y; }
.m-l { margin-left: $spacer-x; }
.m-x { margin-right: $spacer-x; margin-left: $spacer-x; }
