Italicize when hovering over page title

Site URL: http://www.studio6f.com/

I have made it so that the page titles change to a light grey when they're hovered over with your mouse, as well as when you navigate to a page - it turns grey to indicate what page you're on. Is there a way to make these page titles italicize instead? I think it would look a lot cleaner and fit better with our black and white theme. The grey feels disjunctive. Thoughts?

Add to Home > Design > Custom CSS

.nav-item a:hover span {
    font-style: italic;
}
.nav-item.active a span {
    font-style: italic;
}

Hey! I've put this code in and added important; too but it doesn't seem to be working :(

I edited it here because I wanted to italicise all links but it still doesn't work -- the code above works though
