Numbering in section headings #723

Is it possible to enable numbering of section headings in the output? Without it, the print preview can be a little confusing as you have to rely entirely on the heading styles to work out which are sub-headings and which are top-level headings.

I agree that this would be a nice feature.

Any updates?

OK, I could customize general.css.

mdbook init --theme to create a new book.
Move theme/ to your existing book directory.
Append the lines below to theme/css/general.css.

body {
    counter-reset: section -1;
}
h1 {
    counter-reset: subsection 0;
}
h1::before {
    counter-increment: section;
    content: counter(section) ": ";
}
h2::before {
    counter-increment: subsection;
    content: counter(section) "." counter(subsection) ": ";
}
