# Styling

## <a id="style-properties"></a>Style Properties

The following style properties can be used in CSS stylesheets to customize the appearance of this component.

To apply values to these properties globally in your application UI, place them in a CSS block using the `html {…​}` selector. See [Lumo Style Properties](https://vaadin.com/docs/v24/styling/lumo/lumo-style-properties.md) for more information on style properties.

> **Note: Input Field Components Shared Styles**
>
> Style properties whose names start with `--vaadin-input-field` are shared among all input field components. To apply them only to a specific type of component, use an element selector like `vaadin-text-field {…​}`
