Tom,
nice tweak with “page-id-xxx”. Did not notice this before.
But the transparent background is fine, I need to style the text color.
Found out, this is working:
'page-id-106 .main-nav ul ul li a:any-link {
color: #030303;
}
.page-id-106 .main-nav ul ul li[class*="current-menu-"] a:any-link {
color: #030303;
}
Thank you for the hint.
