    The following state attributes are available for styling:

    Attribute Description Part name
    invalid Set when the element is invalid :host
    opened Set when the date selector overlay is opened :host
    readonly Set when the element is readonly :host
    disabled Set when the element is disabled :host
    today Set on the date corresponding to the current day date
    focused Set on the focused date date
    disabled Set on the date out of the allowed range date
    selected Set on the selected date date

    If you want to replace the default input field with a custom implementation, you should use the <vaadin-date-picker-light> element.

    In addition to <vaadin-date-picker> itself, the following internal components are themable:

    • <vaadin-date-picker-text-field>
    • <vaadin-date-picker-overlay>
    • <vaadin-date-picker-overlay-content>
    • <vaadin-month-calendar>

    Note: the theme attribute value set on <vaadin-date-picker> is propagated to the internal themable components listed above.
