Navbar on pure CSS

Elements in navigation bar can have 2 states:

  • Inactive
  • Active

There are 3 different arrows between these states (there are 4 but we’re using only 3):

  • inactive-inactive navigation-bar-1
  • active-inactive navigation-bar-2
  • active-active navigation-bar-3

In order not to use z-index I set elements in opposite order.
