Btw, I'm now using it at:

	https://linuxtv.org/downloads/v4l-dvb-apis-new/index.html

As we use a dark theme at linuxtv.org since ever.

It was built with the following script:

	CSS=linuxtv.css
	THEME=sphinx_rtd_dark_mode

	cat << EOF > $CSS
	  html body {
	    font-family: arial,helvetica,sans-serif;
	    margin: 0px;
	    padding: 0px;
	  }
	  html[data-theme='dark'] body {
	    color: white !important;
	  }
	  html[data-theme='dark'] .sig-name {
	    color: green !important;
	  }
	  html[data-theme='dark'] .wy-menu-vertical a {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h1, html[data-theme="dark"] h2, html[data-theme="dark"] h3 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h4, html[data-theme="dark"] h5, html[data-theme="dark"] h6 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h7, html[data-theme="dark"] h8, html[data-theme="dark"] h9 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] .wy-nav-content a, html[data-theme="dark"] .wy-nav-content a:visited {
	    color: #ffcc00 !important;
	  }
	EOF

	make SPHINXDIRS='media' CSS='$CSS' THEME='$THEME' htmldocs

Thanks,
