Change background and font color of date picker widget input field

Hello there, can I get the css to make the calendar input background white and the font black just like the rest of the form. for example after the client choose the date from the calendar, I want the box back ground white and the chosen date Black

Please add the Custom CSS below to each Date Picker widget:

div#datepicker input.form-control {

    background-color: white !important;

    color: black !important;

}

I have added this in the date pickers of Room 1, you can go ahead and add the rest.
