Ok,
Great strides have been made on my first EPuB book.
Just 4 days ago, I knew only how to do basic programming in HTML0, and now I'm processing an EPuB file.
So far, I've managed to learn, understand, and create my own:
mimetype file,
META-INF\container.xml file,
OEBPS\content.opf file,
OEBPS\Text\*.html files (my book files)
OEBPS\IMG\*.jpg files (my illustrations and images)
The last two are still in the making, but are not hard to due to past experience...
I think I will understand toc.xml just fine, with a little more research,
The Wiki has been a great help, as well as seeing other published books, and comparing them to my own creation.
But I don't get the stylesheet.CSS file at all yet.
It appears different from HTML and XML programming.
Is stylesheet.css absolutely necessary?
Like, it appears to me to be a document describing margins, fonts and sizes, and more other primary data for the garbage collection.
If I would remove the file from an ebook, would it default to some default setting somehow?
I understand that a stylesheet.css could make an ebook appear unique, and allows it to stand out from other ebooks,
but what if I'm perfectly happy with the fonts available in most ebook readers?
Tell me if I'm not getting something!
