Animations

Bootstrap offers two animation styles for spinners. The animation style can be configured with the animation property. An animation style must always be provided when creating a spinner.

Border Spinner - border

import Spinner from 'react-bootstrap/Spinner';

function GrowExample() {
  return <Spinner animation="grow" />;
}

export default GrowExample;

Variants

All standard visual variants are available for both animation styles by setting the variant property. Alternatively spinners can be custom sized with the style property, or custom CSS classes.

      <Spinner animation="border" variant="secondary" />
      <Spinner animation="border" variant="success" />
      <Spinner animation="border" variant="danger" />

      <Spinner animation="grow" variant="light" />
      <Spinner animation="grow" variant="dark" />
    </>
  );
}

export default VariantsExample;

Sizing

In addition to the standard size, a smaller additional preconfigured size is available by configuring the size property to sm.

import Spinner from 'react-bootstrap/Spinner';

function SizesExample() {
  return (
    <>
      <Spinner animation="border" size="sm" />
      <Spinner animation="border" />
      <Spinner animation="grow" size="sm" />
      <Spinner animation="grow" />
    </>
  );
}

export default SizesExample;

Buttons

Like the original Bootstrap spinners, these can also be used with buttons. To use this component out-of-the-box it is recommended you change the element type to span by configuring the as property when using spinners inside buttons.

import Button from 'react-bootstrap/Button';
import Spinner from 'react-bootstrap/Spinner';

function ButtonExample() {
  return (
    <>
      <Button variant="primary" disabled>
        <Spinner
          as="span"
          animation="border"
          size="sm"
          role="status"
          aria-hidden="true"
        />
        <span className="visually-hidden">Loading...</span>
      </Button>{' '}
      <Button variant="primary" disabled>
        <Spinner
          as="span"
          animation="grow"
          size="sm"
          role="status"
          aria-hidden="true"
        />
        Loading...
      </Button>
    </>
  );
}

export default ButtonExample;

Accessibility

To ensure the maximum accessibility for spinner components it is recommended you provide a relevant ARIA role property, and include screenreader-only readable text representation of the spinner's meaning inside the component using Bootstrap's visually-hidden class.

The example below provides an example of accessible usage of this component.
