Close button

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.

html
<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.

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

Dark variant

Deprecated in v5.3.0
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.

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.

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

CSS

Variables

Added in v5.3.0

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.

--#{$prefix}btn-close-color: #{$btn-close-color};
--#{$prefix}btn-close-bg: #{ escape-svg($btn-close-bg) };
--#{$prefix}btn-close-opacity: #{$btn-close-opacity};
--#{$prefix}btn-close-hover-opacity: #{$btn-close-hover-opacity};
--#{$prefix}btn-close-focus-shadow: #{$btn-close-focus-shadow};
--#{$prefix}btn-close-focus-opacity: #{$btn-close-focus-opacity};
--#{$prefix}btn-close-disabled-opacity: #{$btn-close-disabled-opacity};
--#{$prefix}btn-close-white-filter: #{$btn-close-white-filter};
