Good day!
Sure; seems you are using more then one css term class to control this; one is for the homepage and the other one is for all other pages. So I would do this;
since you’ve already done the opacity to the .home class like so;
.home .site-header, .home .main-navigation ul ul a, .home #header-right ul ul a, .home .site-header .cart-content-details {
background-color: rgba(255, 255, 255, 0.7);
}
the other css code that controls it for all other pages is this one;
.site-header, .main-navigation ul ul a, #header-right-menu ul ul a, .site-header .cart-content-details {
background-color: rgb(255, 255, 255);
}
so that one you would also change to;
.site-header, .main-navigation ul ul a, #header-right-menu ul ul a, .site-header .cart-content-details {
background-color: rgb(255, 255, 255, 0.7);
}
and all should work perfect. Let us know ??
