I'm using Moodle 3.10+ (Build: 20210108) with the Boost theme 2020110900 and I would like to change the default layout of the books. Currently the content of a book is next to the table of contents, which reduces the space for viewing the content. I would like the content to occupy the entire available width, leaving the ToC above or below it. I tried extensively to do this using SCSS, but unfortunately I couldn't.
Can someone around here help me?
