Thank you Stephen, but it didn’t quite work. I added it, then again under the existing .entry-content after it didn’t work and still does not display correctly. I checked for syntax errors. I should say that when I had the sharing buttons from Jetpack at the bottom of posts enabled, it seemed to work out nicely. I don’t have a use for those buttons anymore though and so took them out.
The page does display correctly for a split second when it’s refreshed but then pulls back to the end of the text.
