I'm having a bit of an issue where I am using the Content block and attempting to make some portion of the text <h3> and some portion plain <p>. The issue is that if I highlight what I want to be the header and change the style from the dropdown to h3, it surrounds the entire text <h3> tags and gets rid of any paragraph structure.

Is there a way to select styles from within this editor? I can personally go into the HTML and do it but the non computer friendly users of the site are struggling.

Thanks for any help you can give!
