Emphasize menu also in other languages the site is translated

Hi,
I’ve asked to emphasize the menu with topic #210053 and solved it wonderfully! The point is that duplicating the page for english version with WPML this doesn’t work any more. I suppose I have to modify little bit the css that Ismail sent me:

.widget_nav_menu .current_page_item a {
color: red !important;
}
.current-menu-ancestor a, .current-menu-item a {
color: red !important;
}

Can you suggest me how ? Thank you, Nona
