Background header with menu movil in PC right

Hi,

Ying told me to put this code and it works, but how could I make it appear on the right side of the screen?

.main-navigation .menu-toggle, .sidebar-nav-mobile:not(#sticky-placeholder) {
    display: block;
}
.main-navigation ul, .gen-sidebar-nav, .main-navigation:not(.slideout-navigation):not(.toggled) .main-nav > ul, .has-inline-mobile-toggle #site-navigation .inside-navigation > *:not(.navigation-search):not(.main-nav) {
    display: none;
}

Thanks.
