select dropdown icon

Hi,

I have a selectbox with a dropdown-arrow for screens smaller than 992 pixels.
This works great. But when the screen is smaller than 700px, this dropdown-arrow dissapear.

It’s the class: <span class="berocket_aapf_widget_show show_button mobile_hide"><i class="fa fa-angle-left "></i></span> with the ::before element.

Why it dissapear below breakpoint 700px?

regards,

Roland
