Custom Bootstrap 3 Navbar - Justify Links - html

Question

So after reading several similar questions and some trial and error (mostly error) I am still trying to get this sorted out.
The links on the custom nav bar we created are left justified.
|link link link link ....................... | (all left justified)
What we are trying to achieve is evenly spaced links within the custom nav bar.
| link .... link ..... link ..... link .... link | (where they spread out evenly like so.
The css is included. Not certain where I am going wrong but any help would be appreciated.

Answer 1

try this:
.navbar-custom .navbar-nav > li > a {
margin-right: 50px;
}
Play with the spacing until you get the one you want.

Answer 2

When you compile Bootstrap with Less, you can use the following code:
.nav.navbar-nav {
&:extend(.nav-justified all);
}
