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 code={`<a href="#" class="d-inline-flex focus-ring py-1 px-2 text-decoration-none border rounded-2">
    Custom focus ring
  </a>`} />

## 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 code={`<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>`} />

`.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.

<ScssDocs 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 code={`<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>`} />

### Sass variables

Customize the focus ring Sass variables to modify all usage of the focus ring styles across your Bootstrap-powered project.

<ScssDocs 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 code={getData('theme-colors').map((themeColor) => `<p><a href="#" class="d-inline-flex focus-ring focus-ring-${themeColor.name} py-1 px-2 text-decoration-none border rounded-2">${themeColor.title} focus</a></p>`)} />

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]])
