Use the: not () selector to determine whether the form displays borders

Add a border to the element first

/ * add a border * / .nav li {border-right: 1px solid # 666;}

Remove the border for the last element

/ * remove the border * / .nav li:last-child {border-right: none;}

But don't do this, use the: not () pseudo class to achieve the same effect:

.nav li:not (: last-child) {border-right: 1px solid # 666;}

Of course, you can also use .nav li + li, but: not () is clearer and readable.
