For what it's worth, if you're using Pandoc, you can set the HTML output to be "standalone" based on a simple template.[0] You can also include a standard header and footer to be automatically inserted for each generated page.

    pandoc \
      --standalone \
      --css=/style.css \
      --highlight-style=code-highlight.theme \
      --variable=lang:en \
      --include-before-body=navbar.html \
      --include-after-body=footer.html \
      --template=template.html \
      $MD -o $HTML

I use a variation of this command in a bash script to generate my entire static site.[1] A friend improved upon my script with a Go implementation that does some more advanced stuff, but still compiles Markdown to HTML using this command under the hood.[2]
