+title: Focus ring
+description: Utility classes that allows you to add and modify custom focus ring styles to elements and components.
+group: helpers
+toc: true
+added: "5.3"
+---
+
+The `.focus-ring` helper removes the default `outline` on `:focus`, replacing it with a `box-shadow` that can be more broadly customized. The new shadow is made up of a series of CSS variables, inherited from the `:root` level, that can be modified for any element or component.
+
+## Example
+
+Click directly on the link below to see the focus ring in action, or into the example below and then press <kbd>Tab</kbd>.
+
+{{< example >}}
+<a href="#" class="d-inline-flex focus-ring py-1 px-2 text-decoration-none border rounded-2">
+  Custom focus ring
+</a>
+{{< /example >}}
+
+## Customize
+
+Modify the styling of a focus ring with our CSS variables, Sass variables, utilities, or custom styles.
+
+### CSS variables
+
+Modify the `--bs-focus-ring-*` CSS variables as needed to change the default appearance.
+
+{{< example >}}
+<a href="#" class="d-inline-flex focus-ring py-1 px-2 text-decoration-none border rounded-2" style="--bs-focus-ring-color: rgba(var(--bs-success-rgb), .25)">
+  Green focus ring
+</a>
+{{< /example >}}
+
+`.focus-ring` sets styles via global CSS variables that can be overridden on any parent element, as shown above. These variables are generated from their Sass variable counterparts.
+
+{{< scss-docs name="root-focus-variables" file="scss/_root.scss" >}}
+
+By default, there is no `--bs-focus-ring-x`, `--bs-focus-ring-y`, or `--bs-focus-ring-blur`, but we provide CSS variables with fallbacks to initial `0` values. Modify them to change the default appearance.
+
+{{< example >}}
+<a href="#" class="d-inline-flex focus-ring py-1 px-2 text-decoration-none border rounded-2" style="--bs-focus-ring-x: 10px; --bs-focus-ring-y: 10px; --bs-focus-ring-blur: 4px">
+  Blurry offset focus ring
+</a>
+{{< /example >}}
+
+### Sass variables
+
+Customize the focus ring Sass variables to modify all usage of the focus ring styles across your Bootstrap-powered project.
+
+{{< scss-docs name="focus-ring-variables" file="scss/_variables.scss" >}}
+
+### Sass utilities API
+
+In addition to `.focus-ring`, we have several `.focus-ring-*` utilities to modify the helper class defaults. Modify the color with any of our [theme colors]({{< docsref "/customize/color#theme-colors" >}}). Note that the light and dark variants may not be visible on all background colors given current color mode support.
+
+{{< example >}}
+{{< focus-ring.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<p><a href="#" class="d-inline-flex focus-ring focus-ring-{{ .name }} py-1 px-2 text-decoration-none border rounded-2">{{ title .name }} focus</a></p>
+{{- end -}}
+{{< /focus-ring.inline >}}
+{{< /example >}}
+
+Focus ring utilities are declared in our utilities API in `scss/_utilities.scss`. [Learn how to use the utilities API.]({{< docsref "/utilities/api#using-the-api" >}})
