Not much luck here. I went to the Styles in HTML editor behavior and click on the help link, to learn how to use the feature. No Help file found! I was also unable to find any documentation for this feature. I got the editor to recognize one style and it turned the default text gray and very small.
here is the link:tblmain_content_Insert.php
Attached is the style sheet, we would like to add all the styles.
