# Disabling the Default Theme in Flow

Although not a recommended approach to styling Vaadin applications, the default Lumo theme can be disabled using the `@NoTheme` annotation. This is applied to the same class to which you would normally apply the [`@Theme` annotation](https://vaadin.com/docs/v24/styling/application-theme.md#applying-a-theme).

```java
@NoTheme
public class Application implements AppShellConfigurator {
    …
}
```

With the Lumo theme disabled, Vaadin components will load with only the most basic CSS required for them to be functional.
