Solved Change Color of One Menu Item - Style 10

https://intellicureinc.wpengine.com/

I'm using Style 10, but the client wanted the "Sign Up Today" option to be part of the menu instead of a separate button. However, I can't get the "Sign Up Today" text to display white instead of blue like the rest of the menu. I gave it a custom class of .sign-up and used the code .sign-up .dp_regular_menu_0.et_pb_fullwidth_menu ul li a {color:#fff!important;}

This had no effect. Please advise.

 

Fixed with the help of a previous post. The code that worked is .dp_regular_menu_0.et_pb_fullwidth_menu .fullwidth-menu-nav>ul>li:last-child a {color:#fff!important;}
