+description: Use the custom vertical rule helper to create vertical dividers like the `<hr>` element.
+group: helpers
+toc: true
+added: "5.1"

+
+## How it works
+
+Vertical rules are inspired by the `<hr>` element, allowing you to create vertical dividers in common layouts. They're styled just like `<hr>` elements:
+
+- They're `1px` wide
+- They have `min-height` of `1em`
+- Their color is set via `currentColor` and `opacity`
+
+Customize them with additional styles as needed.
+
+## Example
+
+{{< example >}}
+<div class="vr"></div>
+{{< /example >}}
+
+Vertical rules scale their height in flex layouts:
+
+{{< example >}}
+<div class="d-flex" style="height: 200px;">
+  <div class="vr"></div>
+</div>
+{{< /example >}}
+
+## With stacks
+
+They can also be used in [stacks]({{< docsref "/helpers/stacks" >}}):
+
+{{< example >}}
+<div class="hstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border ms-auto">Second item</div>
+  <div class="vr"></div>
+  <div class="bg-light border">Third item</div>
+</div>
+{{< /example >}}
