I'd advise against doing this. White text on a black background is hard to read for some people, which is why most "dark mode" stylesheets are not-really-white on dark-grey. Black text on a white background is fine, of course.

I think this will also have issues with all the other colours on the site, such as the greys used for tables, link colours, etc etc.

I would recommend that if you want to have a dark mode for this site, that you find a third-party theme where this stuff is figured out by other people! Recent versions of bootstrap (v5.3+) have a dark mode, for example, which handles these contrast and colour theory issues.
