Make top navigation menu one row

I'm trying to make my top navigation menu one row, but every time I try doing this, the entire header moves slightly to the right. I think this is because of the cart icon. What code would fix this? I added this code but the alignment isn't good across screen sizes on desktop. 

I'm currently using this code: 

@media screen and (min-width: 992px) {
nav.header-nav-list {
    flex-wrap: nowrap;
  margin-left:18vw!important;
}
}

@media screen and (min-width: 992px)  {
.header-title {
    width: 20% !important;
    flex: 1 1 20% !important;
    margin-left:18vw!important;
  }}
