CircularProgress API
The API documentation of the CircularProgress React component. Learn more about the props and the CSS customization points.
Import
import CircularProgress from '@material-ui/core/CircularProgress';
// or
import { CircularProgress } from '@material-ui/core';
You can learn more about the difference by reading this guide.
ARIA
If the progress bar is describing the loading progress of a particular region of a page,
you should use aria-describedby to point to the progress bar, and set the aria-busy
attribute to true on that region until it has finished loading.
Props
| Name | Type | Default | Description | 
|---|---|---|---|
| classes | object | Override or extend the styles applied to the component. See CSS API below for more details. | |
| color | 'primary' | 'secondary' | 'inherit'  | 
'primary' | The color of the component. It supports those theme colors that make sense for this component. | 
| disableShrink | bool | false | If true, the shrink animation is disabled. This only works if variant is indeterminate. | 
| size | number | string  | 
40 | The size of the circle. If using a number, the pixel unit is assumed. If using a string, you need to provide the CSS unit, e.g '3rem'. | 
| thickness | number | 3.6 | The thickness of the circle. | 
| value | number | 0 | The value of the progress indicator for the determinate and static variants. Value between 0 and 100. | 
| variant | 'determinate' | 'indeterminate' | 'static'  | 
'indeterminate' | The variant to use. Use indeterminate when there is no progress value. | 
The ref is forwarded to the root element.
Any other props supplied will be provided to the root element (native element).

classesobject prop. - With a global class name.
 - With a theme and an
