How it works

Modern CSS provides powerful tools for animating top layer elements (popovers, dialogs):

  • @starting-style defines the initial state before the element appears
  • transition-behavior: allow-discrete enables animating discrete properties like display and overlay
  • The :popover-open pseudo-class targets the open state
