Tab Module - disable auto open tab in mobile view

I’m referencing this post:

I tried to add the code, but it hasn’t worked for me - please can you check:

https://shotkit.com/brands - on a phone, I’d like the first tab to remain closed until clicked.

Code added to page:

jQuery(document).ready(function() {
var width = jQuery(window).width();
activetab = jQuery(’.fl-tabs’).find(’.fl-tab-active’);
if (width <= 767) {
activetab.find(’.fa’).addClass(‘fa-plus’);
activetab.removeClass(‘fl-tab-active’);
}
})

Thanks!!
