Interactive book - text overrides


I'm wondering where I can customize the display of the navigation in the attached screenshot. Specifically, I'l like to have it say "Part x" (and remove the "/y". I've navigated to the Text overrides section of the book, and tried to make a few changes, but have not been successful. thanks.

Hi kylemackie,

I'm afraid you cannot change this in the text overrides section. You should be able to  use a PHP hook, to add your own CSS-file to the content type. Please visit the Visual Changes page for more details.
