How to change colour of close icon of promo box in mobile view

Hi guys,

I'm trying to change the colour of the close icon of the promotional pop-up box in mobile view, but can't seem to change it from the default grey.

I'm currently using this code:

@media only screen and (max-width: 767px) {

  .sqs-slide-wrapper[data-slide-type="popup-overlay"] .sqs-slide-container[data-slide-type="popup-overlay"] .sqs-popup-overlay-close {
    color: #16340A !important;
  }
}

Can anyone help? @tuanphan or @Beyondspace maybe? 🙂

Thanks,
Rhonda
