title: create single, standalone html bookdown file w/gitbook format & style
body: <p>How do I create a single, standalone bookdown html file that retains the gitbook format/style? Using the bookdown demo, my goal is to create a single .html file that I can share or publish to my website. I want to retain the gitbook style (table of contents, layout, color, etc) but I don't want the format as gitbook or epub; I want the format as a single .html file.</p>
  
  <p><a href="https://stackoverflow.com/questions/40976073/bookdown-single-html-output-file">This post is related</a> but does not answer my question. When I add 'split_by:none' to my _output.yml file it does create a single html file. But that .html file is still not a standalone document; if I copy and paste it elsewhere it does not retain the layout, style, and functionality. How can I achieve a single, standalone html file with the gitbook format/style using bookdown?</p>

    split_by: none
