/* The sticky class is added to the navbar with JS when it reaches its scroll position */
.sticky {
  position: fixed;
  top: 0;
  width: 100%;
}

/* Add some top padding to the page content to prevent sudden quick movement (as the navigation bar gets a new position at the top of the page (position:fixed and top:0) */
.sticky + .content {
  padding-top: 60px;
}
