Hi Eric,
Thank you. The hard part was finding the ID for the custom home link. I found this tutorial which explained how to not only find the ID of the custom home link on the navigation bar, but also what code to use in the style.css

Just in case someone needs the same information.
Thanks for pointing me in the right direction.
