Using Pressbooks Custom CSS, Styling, Themes

Hello,
Is it possible to create CSS styles from scratch, or do we always have to select one of the 21 Pressbooks styles and then create an additional custom CSS?

Hi Miguel - on Pressbooks Enterprise networks and on Pressbooks.pub you always have to select one of the 21 themes available. You can’t create your own theme, but you can heavily modify a theme with custom CSS. -Mich
