Bootstrap 5 Close Button

Close button

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

Other frameworks

CoreUI components are available as native Angular, React, and Vue components. To learn more please visit the following pages.


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>

Dark variant

Deprecated in v5.0.0
Heads up! As of v5.0.0, the .btn-close-white class is deprecated. Instead, use data-coreui-theme="dark" to change the color mode of the close button.

Add data-coreui-theme="dark" to the .btn-close, or to its parent element, to invert the close button. This uses the filter property to invert the background-image without overriding its value.

<div data-coreui-theme="dark">
  <button type="button" class="btn-close" aria-label="Close"></button>
  <button type="button" class="btn-close" disabled aria-label="Close"></button>
