Target a specific container to style on WordPress storefront theme

If for example the shoe tab is second in the nav you could use

nav li:nth-child(2) {
}

For that and let’s say hats are the fourth tab, you would use:

nav li:nth-child(4) {
}

This selects the 2nd and the 4th element that is li inside the nav:

<nav>
  <li></li>
  <li></li> <-this gets selected
  <li></li>
  <li> <-and this gets selected
    <ul>
      <li></li>
    </ul>
  </li>
</nav>
