-{{< callout-soon "helper" >}}
+Stacks offer a shortcut for applying a number of flexbox properties to quickly and easily create layouts in OUDS Web. All credit for the concept and implementation goes to the open source [Pylon project](https://almonk.github.io/pylon/).
+
+{{< callout warning >}}
+**Heads up!** Support for gap utilities with flexbox was recently added to Safari, so consider verifying your intended browser support. Grid layout should have no issues. [Read more](https://caniuse.com/flexbox-gap).
+{{< /callout >}}
+
+## Vertical
+
+Use `.vstack` to create vertical layouts. Stacked items are full-width by default. Use `.gap-*` utilities to add space between items.
+
+{{< example class="bd-example-flex" >}}
+<div class="vstack gap-3">
+  <div class="p-2">First item</div>
+  <div class="p-2">Second item</div>
+  <div class="p-2">Third item</div>
+</div>
+{{< /example >}}
+
+## Horizontal
+
+Use `.hstack` for horizontal layouts. Stacked items are vertically centered by default and only take up their necessary width. Use `.gap-*` utilities to add space between items.
+
+{{< example class="bd-example-flex" >}}
+<div class="hstack gap-3">
+  <div class="p-2">First item</div>
+  <div class="p-2">Second item</div>
+  <div class="p-2">Third item</div>
+</div>
+{{< /example >}}
+
+Using horizontal margin utilities like `.ms-auto` as spacers:
+
+{{< example class="bd-example-flex" >}}
+<div class="hstack gap-3">
+  <div class="p-2">First item</div>
+  <div class="p-2 ms-auto">Second item</div>
+  <div class="p-2">Third item</div>
+</div>
+{{< /example >}}
+
+<!--And with [vertical rules]({{< docsref "/helpers/vertical-rule" >}}):
+
+{{< example class="bd-example-flex" >}}
+<div class="hstack gap-3">
+  <div class="p-2">First item</div>
+  <div class="p-2 ms-auto">Second item</div>
+  <div class="vr"></div>
+  <div class="p-2">Third item</div>
+</div>
+{{< /example >}}-->
+
+<!--## Examples
+
+Use `.vstack` to stack buttons and other elements:
+
+{{< example >}}
+<div class="vstack gap-2 col-md-5 mx-auto">
+  <button type="button" class="btn btn-primary">Save changes</button>
+  <button type="button" class="btn btn-outline-secondary">Cancel</button>
+</div>
+{{< /example >}}
+
+Create an inline form with `.hstack`:
+
+<details>
+<summary>See Bootstrap examples that are incompatible with Orange Unified Design System.</summary>
+<br>
+{{< design-callout-alert >}}
+This variant with an **horizontal layout** (i.e. labels not above the input fields) should not be used because it does not respect the Orange Unified Design System specifications.
+{{< /design-callout-alert >}}
+
+{{< example >}}
+<div class="hstack gap-3">
+  <input class="form-control me-auto" type="text" placeholder="Add your item here..." aria-label="Add your item here...">
+  <button type="button" class="btn btn-primary">Submit</button>
+  <div class="vr"></div>
+  <button type="button" class="btn btn-outline-secondary">Reset</button>
+</div>
+{{< /example >}}
+</details>-->
