Because each piece had a title, preamble and a main text part, I could not make a coherent accordion. In addition, every text part was so long that you have to scroll up to close it. I therefore wanted a closing function at the bottom of each text component. Late one evening, I asked the NoNumbers forum if and how I could do this. Early the next morning I had a response from Peter with a suggestion on how to do it. Top Service!
The resulting style settings and code for the article you will find in NoNumbers Forum.
