Sorry for the late reply, but here is what fixed it. I’m using flexbox inside a the text module of the Divi theme by Elegant Themes. There were additional line breaks added that were not in my code. The were visible when inspecting the code via Chrome. They appeared around code that had been commented out. The comments were bracketed with /…./ so I don’t know what the issue is, but as they were notes for me, I removed them. The breaks promptly disappeared and all is well. thank you both for your input.
