Support CoreUI Development

CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.

You can support our Open Source software development in the following ways:

  • Buy the CoreUI PRO and get access to all PRO components, features, templates, and dedicated support.
  • Hire Us! We create stunning designs, high-conversion landing pages, functional mobile apps and reliable web services – everything you need to offer your products or services online and always stay a tap away from your customers.
  • Give us a star ⭐️ on Github.


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


While shadows on components are disabled by default in CoreUI for 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).

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



$box-shadow:                  0 .5rem 1rem rgba($black, .15);
$box-shadow-sm:               0 .125rem .25rem rgba($black, .075);
$box-shadow-lg:               0 1rem 3rem rgba($black, .175);
$box-shadow-inset:            inset 0 1px 2px rgba($black, .075);
