This is a follow-up on a previous thread:
The Twenty-Eleven theme applies styles to the visual editor which make it hard to encourage authors to do the right thing regarding structure. (For example, use of a display font encourages them to make presentation decisions in the editor. Also, the uppercase transform on H3 makes it difficult to encourage authors to write with title case and let the CSS transform in the presentation layer.)
Is there now a way to change those back-end styles with Custom CSS?
