A5 portrait with smaller margins

Hey everyone,

We have started on making Bloom books from the popular Cat and Dog series. We will make them available for Phone and Print. Since they are Creative Commons licensed, we will share them via Bloomlibrary.org


We would like to adjust the margins on the standard A5 Portrait book. So, we created a CustomBookStyles.css. (see attached)

?? What we don’t know is; How to control the gutter margin.

Any help is highly appreciated.

(Attachment customBookStyles.css is missing)

I believe this was addressed here: Adjusting margins on Basic books.

If not, please clarify the question.
