## 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 code={`<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.

<Example code={`<button type="button" class="btn-close" disabled aria-label="Close"></button>`} />

## Dark variant

<DeprecatedIn version="5.3.0" />

<Callout type="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" code={`

`} />

## CSS

### Variables

<AddedIn version="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.
