How to modify the content width of my Jupyter book

[quantitative-technologies]

I want to make the middle content column wider, and also make the total page width larger since it only uses less than 2/3 of the screen width when I read the book in my web browser.

How can I do it?

There is a section in the guides: Custom CSS or JavaScript. However, I am not a web developer, and I don't see any explanation there of how to do my desired customization.

I have also posted a question on SO about this.

Hi @quantitative-technologies , the best way to go about this would be to create your CSS file with the desired style rules, and then add them in your _static folder, as shown in https://sphinx-book-theme.readthedocs.io/en/stable/customize/custom-css.html?highlight=Custom%20CSS .

Unfortunately, there's no easy way at the moment, like, passing the screen width to a config variable, etc. You will require knowledge of CSS to do it.
