I am trying to change nav bar\'s one link\'s color while I tried all ways it still has a default color. Here is the code:
Your anchor has .nav-link class, your .nav-item has the custom .signup class. Where did you come up the structure of .nav-link li a.signup?
.nav-link
.nav-item
.signup
.nav-link li a.signup
Try this:
.navbar-light .navbar-nav .nav-item.signup .nav-link { color:#fff; }
