Use the margin and padding spacing utilities to control how elements and
components are spaced and sized. Bootstrap 4 includes a five-level scale for
spacing utilities, based on a 1rem value default $spacer variable. Choose
values for all viewports (e.g., .mr-3 for margin-right: 1rem), or pick
responsive variants to target specific viewports (e.g., .mr-md-3 for
margin-right: 1rem starting at the md breakpoint).
<div class="my-0 bg-warning">Margin Y 0</div>
<div class="my-1 bg-warning">Margin Y 1</div>
<div class="my-2 bg-warning">Margin Y 2</div>
<div class="my-3 bg-warning">Margin Y 3</div>
<div class="my-4 bg-warning">Margin Y 4</div>
<div class="my-5 bg-warning">Margin Y 5</div>
<div class="my-auto bg-warning">Margin Y Auto</div>bootstrap spacing
The classes are named using the format {property}{sides}-{size} for xs
and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

p - for classes that set padding
Where sides is one of:
t - for classes that set margin-top or padding-top

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
