   Thanks. Inspired by that:   
      
   @-moz-document url-prefix("https://developer.mozilla.org/en-US/docs/") {   
     /* lay out horizontally if possible ... */   
     .a11y-menu {   
       display: flex;   
     }   
     /* show nav menu on hover or tab */   
     .page-layout__header:hover, .page-layout__header:focus-within {   
       height:  50vh;   
       overflow: scroll;   
     }   
     /* ... and lay out again */   
     .page-layout__header .menu {   
       display: flex;   
     }   
     /* or minimise */   
     .page-layout__header {   
       height: 3ch;   
       overflow: hidden;   
     }   
   }   
      
   And I learned about the focus-within pseudo-class, too!
