<ul> all of which have class of "level0 level-top parent". However, the last 2 list items have an additional class called "mobile-nav-only" as well as "level0 level-top parent"<li> with the class of "level0 level-top parent" BUT ONLY if that li does NOT have "mobile-nav-only". I believe I need to combine both :last-child and :not pseudo classes but I'm struggling to figure out the correct syntax.
