What this Bootstrap Utility API class does
Set the padding top and bottom property for an element to the same value.
Example usage & available classes
<div class="py-0"></div>
<div class="py-1"></div>
<div class="py-2"></div>
<div class="py-3"></div>
<div class="py-4"></div>
<div class="py-5"></div>
Example override
In the example override below, we are adding the additional class of "py-6" with a value of "6rem". Note that you can update Bootstrap's SASS $spacer variable to add additional margin and padding options. This would be a cleaner method to use rather than using the API because any additional values you add to the $spacer variable would automatically be available for all the margin and padding utilities.
"padding-y": map-merge(
map-get($utilities, "padding-y"),
(
values: map-merge(
map-get(map-get($utilities, "padding-y"), "values"), (
6: 6rem
)
)
)
)
