@Tag("label") @Deprecated(since="24.1", forRemoval=true) public class Label extends HtmlContainer
Deprecated, for removal: This API element is subject to removal in a future version.
Use NativeLabel instead, if you need the HTML <label> element, which is normally not needed within a Vaadin Flow application's high-level components. To use a Label that works in the older style of Vaadin 8 or Java Swing, and can be used both to label a component and to display loose text, an alternative is the Label available in Classic Components. This Label component / <label> element is not meant for loose text in the page - it should only be coupled with another component by using the setFor(Component) or by adding them to it with the HasComponents.add(Component...) method, for example if you use Input.

Component for a <label> element, which represents a caption for an item in a user interface.

Clicking on a label automatically transfers the focus to the associated component. This is especially helpful when building forms with Inputs.

For adding texts to the page without linking them to other components, consider using a Span or a Div instead. If the text should be interpreted as HTML, use a Html (but remember to guard against cross-site scripting attacks).
