## <a id="css-selectors"></a>CSS Selectors

The following CSS selectors can be used in stylesheets to target the various parts and states of the component. See the [Styling documentation](https://vaadin.com/docs/next/styling.md) for more details on how to style components.

> **Important: Not for Shadow DOM**
>
> These selectors should be used in `styles.css` or another stylesheet loaded with the `@StyleSheet` annotation or the `@import` CSS rule. **They do not work in the shadow DOM of Vaadin components**, such as in stylesheets in the `components` sub-folder or loaded with the `@CssImport` annotation’s `themeFor` property.
