Hello,
1 – You can add this css code into Theme Options=>Custom CSS:
.header-container .horizontal-menu {
background: #888;
}
2 – Change menu font color in Theme Options=>Fonts=>Menu font
3 – Activated menu item color is primary color in Theme Options=>Colors. You can add css code into “style.css” file to change it:
.header-container .horizontal-menu #mega_main_menu > .menu_holder .menu_inner > ul > li.current-menu-ancestor > a.item_link .link_content .link_text, .header-container .horizontal-menu #mega_main_menu > .menu_holder .menu_inner > ul > li.current-menu-item > a.item_link .link_content .link_text {
color: #5fb805 !important;
}
Best regards
