# Spinner
[component-header:sl-spinner]
Spinners are used to show the progress of an indeterminate operation.
```html preview
<sl-spinner></sl-spinner>
```
```jsx react
import { SlSpinner } from '@shoelace-style/shoelace/dist/react';
const App = () => (
<SlSpinner />
);
```
## Examples
### Size
Spinners are sized based on the current font size. To change their size, set the `font-size` property on the spinner itself or on a parent element as shown below.
```html preview
<sl-spinner></sl-spinner>
<sl-spinner style="font-size: 2rem;"></sl-spinner>
<sl-spinner style="font-size: 3rem;"></sl-spinner>
```
```jsx react
import { SlSpinner } from '@shoelace-style/shoelace/dist/react';
const App = () => (
<>
<SlSpinner />
<SlSpinner style={{ fontSize: '2rem' }} />
<SlSpinner style={{ fontSize: '3rem' }} />
</>
);
```
### Track Width
The width of the spinner's track can be changed by setting the `--track-width` custom property.
```html preview
<sl-spinner style="font-size: 50px; --track-width: 10px;"></sl-spinner>
```
```jsx react
import { SlSpinner } from '@shoelace-style/shoelace/dist/react';
const App = () => (
<SlSpinner
style={{
fontSize: '3rem',
'--track-width': '6px'
}}
/>
);
```
### Color
The spinner's colors can be changed by setting the `--indicator-color` and `--track-color` custom properties.
```html preview
<sl-spinner style="font-size: 3rem; --indicator-color: deeppink; --track-color: pink;"></sl-spinner>
```
```jsx react
import { SlSpinner } from '@shoelace-style/shoelace/dist/react';
const App = () => (
<SlSpinner
style={{
fontSize: '3rem',
'--indicator-color': 'deeppink',
'--track-color': 'pink'
}}
/>
);
```
