I am trying to set up more than one style of Blockquote in an RTE. Is this possible?
Not without using custom code, since you can’t assign classes to elements within a rich text field or widget.
You can use custom code inside of the RTE that you could target with a style.
I had to do something similar for a client. The blockquotes had a default color and to change it I ended up teaching them how to put an embed element inside the RTE like this:
< blockquote color=“the-color-they-wanted” >Their quote< /blockquote >
(sorry for the spaces, it would just make it into a quote)
