-## 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`.
+## Basic Close Button
 
 {{< example >}}
 <button type="button" class="btn-close" aria-label="Close"></button>
 {{< /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.
+## Dark Close Button
 
 {{< example >}}
-<button type="button" class="btn-close" disabled aria-label="Close"></button>
-{{< /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" >}}
-<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 class="bg-dark p-2">
+  <button type="button" class="btn-close btn-close-white" aria-label="Close"></button>
 </div>
 {{< /example >}}

+## Light
 
-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.
+{{< example >}}
+<div data-bs-theme="light" class="bg-body p-2">
+  <button type="button" class="btn-close" aria-label="Close"></button>
+</div>
+{{< /example >}}
