Dear squarespace community, 

I have animated underline for my navigation links. However the space between the underline and the link is quite big. How do I reduce the space so that the underline is directly below the navigation link? 

This is the code I use:

 /* navigation underline animation */
.header-nav-item::after {
  content: '';
  background: #FFFFFF; //color
  height: 2px; //thickness
  width: 0;
  display: block;
  margin-top: 1px !important;
  transition: width 0.5s; //animation speed
  margin: 0 auto;
}

.header-nav-item:hover::after {
  width: 100%;
}

.header-nav-item--active a {
    background-image: none !important;
}

.header-nav-item::after {
    top: -10px;
    position: relative;
