Did you change something to do with the CSS used for each topic?
I think I must have inadvertently changed something with the CSS because older topics (that I did not create) are now doing the same thing. Unfortunately I was placed into this position without much training when our technical writer left the company.
Do you recommend any tutorials that may help me figure out what I did?
Check to see what CSS is being used in the project folders & maybe go back to a backup copy to retrieve one?
First, try clicking the little CSS button and choosing None.
See if that will "clear" the problem. If it does, it means there is something in the CSS causing it to be wonky.
But even if that's the case, I'd be curious to see if things look okay or the same in the RoboHelp Preview as well as the final output. All may behave differently!
