That is correct. My mistake. It is correctly written on the CSS file.

When you opened the epub in the calibre Editor did you run 'Check Book' to make sure there were no errors? Does the edited epub open OK in the calibre Viewer?

There are no errors, just a few warnings about some -webkit specific attributes.

I don't use GPB often enough to know its quirks. Have you tried any other Android reading apps to see if your book is valid there?

Mmm no, I haven't tried other apps. But I do not wish to change from reading app, my tablet is very old and from previous attemps at reading other books, this is the one which works the best on my device.

I'm not even sure changing the black CSS to white is changing anything, since those bars do not appear on the Calibre viewer.

Perhaps there's another solution?

Actually, jackie_w makes a good point. Are you using calibre's editor, or Sigil, or are you just opening the epub zip file and viewing the internal docs?

I'm using calibre's editor.

If you set body Background to Black, you would also need to set text to: color: white

This ebook has no text, just images of text.
