## 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).

{{< example class="overflow-hidden" >}}
<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>
{{< /example >}}
