Spacing

Template 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 set `margin`
- `p` - for classes that set `padding`

Where sides 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`
- blank - for classes that set a `margin` or `padding` on all 4 sides of the element

Where size is one of:

- `0` - for classes that eliminate the `margin` or `padding` by setting it to `0`
- `1` - (by default) for classes that set the `margin` or `padding` to `$spacer * .25`
- `2` - (by default) for classes that set the `margin` or `padding` to `$spacer * .5`
- `3` - (by default) for classes that set the `margin` or `padding` to `$spacer`
- `4` - (by default) for classes that set the `margin` or `padding` to `$spacer * 1.5`
- `5` - (by default) for classes that set the `margin` or `padding` to `$spacer * 2`
- `6` - (by default) for classes that set the `margin` or `padding` to `$spacer * 2.5`
- `7` - (by default) for classes that set the `margin` or `padding` to `$spacer * 3`
- `8` - (by default) for classes that set the `margin` or `padding` to `$spacer * 3.5`
- `9` - (by default) for classes that set the `margin` or `padding` to `$spacer * 4`
- `10` - (by default) for classes that set the `margin` or `padding` to `$spacer * 4.5`
- `11` - (by default) for classes that set the `margin` or `padding` to `$spacer * 5`
- `12` - (by default) for classes that set the `margin` or `padding` to `$spacer * 6`

## 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, template 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`.

Centered element

      <div class="mx-auto bg-primary text-white p-2" style="width: 200px;">
        Centered element
      </div>
