With the bevy of experts watching this thread, I have one more problem.
After making changes of the style sheet to lower case, the Sigil file looks great and the calibre epub viewer shows everything well.
However, ADE shows a problem.
Each chapter begins the first paragraph with a graphic as the first letter. Initially, ADE showed the image centered and the text beside it run off the page to the right. I cured the image by changing the css for the image to align: left. I have tried several changes to the css for the text but my lack of knowledge and experience have shined through.
Can someone lead this sinner to the path of true right and proper CSS?
