Editor not enclosing content - SOLVED
I was having a problem where the editor was not enclosing the content and I was either getting content off screen or scroll bars every which way.
I found this solution posted by Peter Thomassen on this page:
Maybe, there is a cleaner solution using several CSS files or style elements, thus omitting the unintended application of CSS properties. I did not investigate this because the above approach solves that issue for me.
It worked for me. Hope it helps someone else.
