@Ceramica,

Try adding this CSS:

@media (max-width:768px){
    .main-navigation .main-nav ul li a {
        padding: 0 !important;
    }

    ul#menu-menu-1 {
        width: 100%;
    }

    ul#menu-menu-1 {
        justify-content: center;
    }
}

Elvin you are a miracle of knowledge Thank you ...
It works great!
