Changing hovering behavior in scss

Question

How can I make the "Menu" Button remain in hover as long as the mouse/pointer remains in the menu? When the pointer points on Twitter for example I want the menu button to show Home.

}

.menu {

  display: inline-block;
  cursor: pointer;
  pointer-events: none;

You can add the same rules inside .menu:

.menu {
...
  &:hover {
    .btn-flip {
      &:after {
        opacity: 1;
        transform: translateY(0) rotateX(0);
      }
      &:before {
        opacity: 0;
        transform: translateY(50%) rotateX(90deg);
      }
    }
