Reply To: Color changes when hovering over the menu

Hello,

You are Most Welcome.

For the background try adding the following Custom CSS:

.header-categories-nav .categories-menu-dropdown .item-level-0>a:hover {
    background: transparent;
}

.vertical-navigation .menu-simple-dropdown li a:hover {
    background: transparent;
}

For the font-size try adding the following Custom CSS:

.header-categories-nav .categories-menu-dropdown .item-level-0>a {
    font-size: 15px;
}

.menu-simple-dropdown li a {
    font-size: 15px;
}

Best Regards.
