CSS

You can override all the class names injected by Material-UI thanks to the classes property. This property accepts the following keys:

Name Description
root Styles applied to the root element.
error Styles applied to the root element if error={true}.
disabled Styles applied to the root element if disabled={true}.
marginDense Styles applied to the root element if margin="dense".
contained Styles applied to the root element if variant="filled" or variant="outlined".
focused Styles applied to the root element if focused={true}.
filled Styles applied to the root element if filled={true}.
required Styles applied to the root element if required={true}.

Have a look at overriding with classes section and the implementation of the component for more detail.

If using the overrides key of the theme, you need to use the following style sheet name: MuiFormHelperText.
