Is there a CDN from where I can fetch the css for syntax highlighting?

I’m using nbconvert to export jupyter notebooks to HTML. By default, the exported notebooks have quite a lot of CSS in the header. I’d like to have all the CSS pulled from CDNs. About 90% of the CSS in the header can be replaced by sourcing However, that still leaves the CSS for syntax highlighting:

<style type="text/css">
.highlight .hll { background-color: #ffffcc }
.highlight  { background: #f8f8f8; }
.highlight .c { color: #408080; font-style: italic } /* Comment */
.highlight .err { border: 1px solid #FF0000 } /* Error */
.highlight .k { color: #008000; font-weight: bold } /* Keyword */
.highlight .o { color: #666666 } /* Operator */

Is there somewhere (some CDN perhaps) that I can pull this from?
