I make a fixed block for the menu.

.header-fixed { position: fixed z-index: 1000 background-color: #ffffff top: 0 }

Question: how to position the unit in the center at any screen resolution?

 .header-fixed { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%); z-index: 1000; background-color: #ffffff; }
