+description: Shorthand helpers that build on top of our flexbox utilities to make component layout faster and easier than ever.
+group: helpers
+toc: true
+---
+
+Stacks offer a shortcut for applying a number of flexbox properties to quickly and easily create layouts in Bootstrap. All credit for the concept and implementation goes to the open source [Pylon project](https://almonk.github.io/pylon/).
+
+## Vertical
+
+Use `.vstack` to create vertical layouts. Stacked items are full-width by default. Use `.gap-*` utilities to add space between items.
+
+{{< example >}}
+<div class="vstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border">Second item</div>
+  <div class="bg-light border">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 >}}
+<div class="hstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border">Second item</div>
+  <div class="bg-light border">Third item</div>
+</div>
+{{< /example >}}
+
+Using horizontal margin utilities like `.ms-auto` as spacers:
+
+{{< 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="bg-light border">Third item</div>
+</div>
+{{< /example >}}
+
+<div class="d-flex" style="height: 200px;">
+<div class="vr"></div>
+</div>
+
+{{< 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 >}}
+
+## 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-secondary">Save changes</button>
+  <button type="button" class="btn btn-outline-secondary">Cancel</button>
+</div>
+{{< /example >}}
+
+Create an inline form with `.hstack`:
+
+{{< example >}}
+<div class="hstack gap-3">
+  <input class="form-control me-auto" type="text" placeholder="Add your item here...">
+  <button type="button" class="btn btn-secondary">Submit</button>
+  <div class="vr"></div>
+  <button type="button" class="btn btn-outline-danger">Reset</button>
+</div>
+{{< /example >}}
