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 PRO components, and dedicated support.
  • Became a sponsor, and get your logo on files or each site of this documentation
  • Give us a star ⭐️ on Github.

Close button

A generic close button for dismissing content like modals and alerts.


Provide an option to dismiss or close a component with .btn-close. Default styling is limited, but highly customizable. Modify the Sass variables to replace the default background-image. Be sure to include text for screen readers, as we’ve done with aria-label.

<button type="button" class="btn-close" aria-label="Close"></button>

Disabled state

Disabled close buttons change their opacity. We’ve also applied pointer-events: none and user-select: none to preventing hover and active states from triggering.

<button type="button" class="btn-close" disabled aria-label="Close"></button>

White variant

Change the default .btn-close to be white with the .btn-close-white class. This class uses the filter property to invert the background-image.

<button type="button" class="btn-close btn-close-white" aria-label="Close"></button>
<button type="button" class="btn-close btn-close-white" disabled aria-label="Close"></button>
