Spinners

The <BSpinner> component can be used to show the loading state in your projects. They're rendered only with basic HTML and CSS as a lightweight Vue component. Their appearance, alignment, and sizing can be easily customized with a few built-in props and/or Bootstrap v5 utility classes.

Spinners can be placed just about anywhere, including inside buttons, alerts, and even <BTable>'s busy slot.

HTML
template
<div class="text-center">
  <BSpinner label="Spinning" class="mx-1" />
  <BSpinner type="grow" label="Spinning" class="mx-1" />
  <BSpinner variant="primary" label="Spinning" class="mx-1" />
  <BSpinner variant="primary" type="grow" label="Spinning" class="mx-1" />
  <BSpinner variant="success" label="Spinning" class="mx-1" />
  <BSpinner variant="success" type="grow" label="Spinning" class="mx-1" />
</div>

Spinner types

Border spinner

Use the default border type spinners for a lightweight loading indicator.

HTML
template
<BSpinner />

Growing spinner

If you don't fancy a border spinner, switch to the grow spinner by setting the prop type to 'grow'. While it doesn't technically spin, it does repeatedly grow!

HTML
template
<BSpinner type="grow" />

Spinner color variants

Spinners use currentColor for their color, meaning it inherits the current font color. You can customize the color using the standard text color variants using the variant prop, or place classes or styles on the component to change its color.

The variant prop translates the variant name to the Bootstrap v4 class .text-{variant}, so if you have custom defined text color variants, feel free to use them via the variant prop.

HTML
template
<template>
  <div>
    <div class="text-center mb-3 d-flex justify-content-between">
      <BSpinner v-for="variant in variants" :key="variant" :variant="variant" />
    </div>

    <div class="text-center d-flex justify-content-between">
      <BSpinner v-for="variant in variants" :key="variant" :variant="variant" type="grow" />
    </div>
  </div>
</template>

<script setup lang="ts">
import {type ColorVariant} from 'bootstrap-vue-next'

const variants = [
  'primary',
  'secondary',
  'danger',
  'warning',
  'success',
  'info',
  'light',
  'dark',
] as ColorVariant[]
</script>

INFO

Why not use border-color utilities? Each border spinner specifies a transparent border for at least one side, so .border-{color} utilities would override that.

Size

Set the prop small to true to make a smaller spinner that can quickly be used within other components.

HTML
template
<BSpinner small class="me-2" />
<BSpinner small type="grow" />

Or, use custom CSS or inline styles to change the dimensions as needed.

HTML
template
<BSpinner style="width: 3rem; height: 3rem" class="me-2" label="Large Spinner" />
<BSpinner style="width: 3rem; height: 3rem" label="Large Spinner" type="grow" />

Alignment

Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily be resized, recolored, and quickly aligned.

Margin

Use margin utilities like .m-5 for easy spacing.

HTML
template
<BSpinner class="m-5" label="Busy" />

Placement

Use flexbox utilities, float utilities, or text alignment utilities to place spinners exactly where you need them in any situation.

Flex

Using flex utility classes:

HTML
template
<div class="d-flex justify-content-center">
  <BSpinner />
</div>

Floats

Using float utility classes:

HTML
template
<div class="clearfix">
  <BSpinner class="float-end" />
</div>

Text align

Using text alignment utility classes:

HTML
template
<div class="text-center">
  <BSpinner />
</div>

Spinners in buttons

Use spinners within buttons to indicate an action is currently processing or taking place. You may also swap the text out of the spinner element and utilize button text as needed.

HTML
template
<BButton variant="primary" disabled class="me-2">
  <BSpinner small />
  <span class="visually-hidden">Loading...</span>
</BButton>
<BButton variant="primary" disabled>
  <BSpinner small />
  Loading...
</BButton>
HTML
template
<BButton variant="primary" disabled class="me-2">
  <BSpinner small type="grow" />
  <span class="visually-hidden">Loading...</span>
</BButton>
<BButton variant="primary" disabled>
  <BSpinner small type="grow" />
  Loading...
</BButton>

Spinner accessibility

Place a hidden label text inside the spinner for screen reader users, via the label prop or label slot. The content will be placed inside the spinner wrapped in a <span> element that has the class visually-hidden, which will make the label available to screen reader users.

For accessibility purposes, each spinner will automatically have a role="status" attribute when a label is provided. You can easily customize the role if required via prop role. The specified role will not be applied when no label is provided.

As well, when no label is provided, the spinner will automatically have the attribute aria-hidden="true" to hide the spinner from screen reader users.
