Styling can only be done visually with the designer or by custom code embeds. Rich Text Elements support nested styles (all H4’s with a RTE) for example but that can only be done when the rich text field is unbound from the collection. The common approach is to create a rich text field on a style guide page, use the same class, then style descendent elements.

I don’t think so. Please explain what elements you wish to style with what values.
