I have applied a theme to my form but the spinner fields have not picked up the same background colour in the input checkbox

my form is here: https://form.jotform.com/hilltopkennels/booking-request

The spinner controls have a white background in the input section, how do i change them to match the other fields on the form?

Please inject the following CSS code to the form so that the background of the spinner field will be transparent.

.form-spinner {

  background: transparent !important; 

}

Thank you!
