Navigation Styling

Here's the code you need to paste inside the dedicated area for Custom CSS Code under the Theme Options Panel  to change the navigation style:

#main-menu .top-menu a {
    font-weight: 400 !important;
    font-size: 16px !important;
}
#main-menu .sub-menu a {
    font-weight: 400 !important;
    font-size: 14px !important;
}

Please adjust the values after your own needs.
