Thank you and you're right, the <div> tags were not really useful. I had doubts about them myself, but thought I might need them later in ways I could not predict. If p.anything overrules simple p, then obviously I don't need them at all. I also had some small poems in later stories, which need different handling too. I had them in <div class="poem"> tags, but I guess <p class="poem"> would suffice. What would I need a <div> tag for, then, I wonder... I'll probably find out with experience.
About the indents, I was not at all sure how to format the book, so to avoid experimenting well into next year, I just copied the formatting of the original paper book, which actually had deeper indents for the first paragraphs, along with the titles. It surprised me too, but it looked okay.
Jellby, Pdurrant and Zelda, have I told you you have been fantastic? I'm so happy to be here among you
