+Easily customize `animation-direction`s by adding the appropriate class.
+
+The available classes:
+
+```scss
+.animation-direction-normal{
+  animation-direction: normal;
+}
+.animation-direction-reverse{
+  animation-direction: reverse;
+}
+.animation-direction-alternate{
+  animation-direction: alternate;
+}
+.animation-direction-alternate-reverse{
+  animation-direction: alternate-reverse;
+}
+```
+
+
+
+The following example shows how the class `animation-direction-reverse` was used to reverse the animation direction of a spinner-border.
+
+{{< example >}}
+<div class="spinner-border text-primary animation-direction-reverse" role="status">
+  <span class="visually-hidden">Loading...</span>
+</div>
+{{< /example >}}
