When running rustup doc, this file is opened for me ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/share/doc/rust/html/index.html. I thought I'd use that file in my note taking application, which I have set to a dark theme. However the css for body in that documentation is set to have the color = #333; and the background uses the default color.

This leads to the text becoming hard to read.

I would prefer the text color not to be explicitly set, or if you insist on the dark gray text, making sure that the background color is also set to something light.
