Change color submenu on mobile

Hi,
I can’t change color of submenu on mobile.
It always remains blu and text not is visible.

How can I do?
Thank u for help

Hello there,

To customize it, use this CSS code:

    #mainnav-mobi ul.sub-menu {
      background-color: transparent;
    }

    #mainnav-mobi ul.sub-menu a {
      color: #fff000; 
    } 

Add it to Appearance > Customize > Additional CSS from dashboard.

Regards,
Kharis
