Not able to apply a class to text links

New to Webflow, trying to build out a basic layout. I’m having trouble creating a class that is active for all nav links, so I can edit them all at once. I added the class “nav-link” to all my navigation links but still cannot edit the class as a group, only individually. Went through a few tutorials and it seems like I should be able to just add the new class to the elements and be able to edit the elements as a group but doing that isn’t working for me. Is there something that I’m missing? Any help would be appreciated!
