Example#

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.

{ {< example >} } { {< /example >} }

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.

{ {< example >} } { {< /example >} }

Dark variant#

{ {< deprecated-in "5.3.0" >} }

{ {< callout warning >} } Heads up! As of v5.3.0, the .btn-close-white class is deprecated. Instead, use data-bs-theme="dark" to change the color mode of the close button. { {< /callout >} }

Add data-bs-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.

{ {< example class="bg-dark" >} }

{ {< /example >} }

CSS#

Variables#

{ {< added-in "5.3.0" >} }

As part of Bootstrap's evolving CSS variables approach, close button now uses local CSS variables on .btn-close for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

{ {< scss-docs name="close-css-vars" file="scss/_close.scss" >} }
