It would be awesome if each individual anvil component has a advanced tab where you can add individual css.
I know its possible to do this using anvil roles => assign the role to a component, but i find it kind of time consuming. Also its possible by using the anvil.js module.
But this way seem very straight forward; you could just add your css; while doing it you see the changes right away in the designer
