I posted on Stackoverflow a couple of questions related to theming bookdown projects. There have been no responses so I hope that, as I continue to struggle with these questions, I may post the queries here (potentially in the hope of reaching the bookdown author).
I would like to do two things:
(1) Remove the theme icon that appears in the toolbar (so that a user cannot change the theme).
(2) Create a new theme based on the standard white theme, or modify the standard white theme (I don't want to do a great deal: just a few changes to help the book/manual I have developed fit within the theme of the new website we are developing (I work for a wildlife conservation charity).
I have been unable to find information on (1) in the bookdown documentation or elsewhere, and, although there is a little information on css in the bookdown documentation, and I have looked at style.css, I haven't been able to figure out what I need to resolve (2).
With grateful thanks.
