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/).
{{< 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 >}}
<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 >}}
And with [vertical rules]({{< docsref "/helpers/vertical-rule" >}}):
{{< 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..." aria-label="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 >}}
