This property accepts the following keys: - `root` - `dense` - `label` - `flatPrimary` - `flatAccent` - `flatContrast` - `colorInherit` - `raised` - `keyboardFocused` - `raisedPrimary` - `raisedAccent` - `raisedContrast` - `disabled` - `fab` Have a look at [overriding with class names](/customization/overrides#overriding-with-class-names) section 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`.
