Oh. So it's much better to go to each and individual style properties and change them from there?
Is there a general guide to what the correct terms are for what?Well it really depends on what you want to do. If you want to change the border colors globally, we have a color palette property for that so you should change it there. If you want just the sidebar block border to change and only that border color you'd want to edit the property.
If you want to give me an idea of what you're looking to change I can recommend what I would do.
