Any other properties supplied will be spread to the root element ([ButtonBase](/api/button-base)).

## CSS API

You can override all the class names injected by Material-UI thanks to the `classes` property.
This property accepts the following keys:
- `root`
- `label`
- `flatPrimary`
- `flatSecondary`
- `outlined`
- `colorInherit`
- `raised`
- `raisedPrimary`
- `raisedSecondary`
- `focusVisible`
- `disabled`
- `fab`
- `mini`
- `sizeSmall`
- `sizeLarge`
- `fullWidth`

Have a look at [overriding with classes](/customization/overrides#overriding-with-classes) section
and the [implementation of the component](https://github.com/mui-org/material-ui/tree/master/packages/material-ui/src/Button/Button.js)
for more detail.

If using the `overrides` key of the theme as documented
[here](/customization/themes#customizing-all-instances-of-a-component-type),
you need to use the following style sheet name: `MuiButton`.

## Inheritance

The properties of the [ButtonBase](/api/button-base) component are also available.
You can take advantage of this behavior to [target nested components](/guides/api#spread).
