<h1>Spacing Utilities</h1>
<p>Set the spacing of an element with the {property}{sides}-{breakpoint}-{size} classes. Omit breakpoint if you want the padding or margin to work on all screen sizes.</p>
<div class="pt-4 bg-warning">I only have a top padding (1.5rem = 24px)</div>
<div class="p-5 bg-success">I have a padding on all sides (3rem = 48px)</div>
<div class="m-5 pb-5 bg-info">I have a margin on all sides (3rem = 48px) and a bottom padding (3rem = 48px)</div>
