Hello,

I have seen many messages about this problem going back years, but unfortunately I was unable to solve it. I have Calibre 8.13 and I am converting from ODT to EPUB. I would like to add extra CSS and according to the manual I should be able to just type it in the window during conversion under Look and Feel -> Styling -> Extra CSS. I have done this but it is not included in the stylesheet.css for my book. I've tried both raw CSS and a path to a file, and can't get it to work.

Here is my CSS (very simple):

.calibre5 {
max-height: 90%;
max-width: 100%;
}

I suspect I'm doing something wrong. How can I get it to work, please?
