Shadows

Add or remove shadows to elements with box-shadow utilities.

Examples

While shadows on components are disabled by default in Bootstrap and can be enabled via $enable-shadows, you can also quickly add or remove a shadow with our box-shadow utility classes. Includes support for .shadow-none and three default sizes (which have associated variables to match).

html

<div class="shadow-none p-3 mb-5 bg-body-tertiary rounded">No shadow</div>
<div class="shadow-sm p-3 mb-5 bg-body-tertiary rounded">Small shadow</div>
<div class="shadow p-3 mb-5 bg-body-tertiary rounded">Regular shadow</div>
<div class="shadow-lg p-3 mb-5 bg-body-tertiary rounded">Larger shadow</div>
