Example 1: bootstrap Margin and padding
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>
Example 2: 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. 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 * 3 auto - for classes that set the margin to auto $spacer defaults to 1rem
