Apply styling to header/footer

[irrationalpie]

The "Styles" page of the viewer preferences mentions there are custom classes for different flow modes, e.g. body.calibre-viewer-paginated and body.calibre-viewer-scrolling. Are there specific classes or ids associated with the headers and footers? I would love to be able to style them specifically, although setting a minimum font size in preferences did fix my main complaint, which is that they were microscopically small on my laptop. I tried looking on github to see how the viewer constructs things, but although I saw references to e.g. something that looked like it could be a 'book-side-margin' class, I couldn't get that to do anything.

After I experimentally tried overriding all text and background colors, I suspect the style sheet may simply not apply to the headers and footers, which might explain why they're in a sans-serif font despite my preference saying to use serif font. Although at least the background/foreground color respects my custom color preferences.

* {
color: black !important;
background-color: white !important;
border-style: dotted !important;
}

This screenshot shows "Chapter 1" (part of the heading) in my normal custom font/background color, with the text below in black and white as per the experiment stylesheet.

The stylesheet does not apply to headers and footers, only to book content. Headers and footers are shown in the UI font, not the book text font, since that would be pretty confusing.

I guess that makes sense. In my mental model, I was thinking of the header and footer as belonging to the book, like a page number or chapter title that's on each written page, so I expected to be able to style it like I was styling the rest of the page. Don't get me wrong, I like the fact that the header and footer apply my custom background and foreground color--it would be rather jarring to have them in a totally different brightness level, the way the toolbar is--but I think that contributed to my confusion. Thanks for explaining!

Indeed in an ebook unlike a pbook headers and footers belong to the reader not the author
