Over on the Kindle forum, there was a post from a would-be publisher who evidently convinced himself/herself that the non-breaking space was the way to insert a chapter break. I pondered this for a while, then realized that the default file that opens up when Sigil is opened reads like this:
<body>
<p> </p>
</body>
I never really thought about that before, since I generally open an html file to start working on a book.
Is there a reason why that non-breaking space is there? Is it just a gentle reminder that we are supposed to add some text?
