Static assets

If you’re coming from Sphinx: this theme’s extra_css param (see Styling ) is the direct equivalent of html_css_files. There’s no direct equivalent of html_js_files/app.add_js_file as a theme param — for custom JS, use Hugo’s own asset pipeline (Hugo Pipes ) at the site level: drop a script in your site’s assets/, process/fingerprint it with resources.Get/fingerprint in a site-level partial override, and add that partial to whichever slot you want it in (e.g. content_footer_items, footer_end).

See Asset pipeline for how this theme’s own FontAwesome/Bootstrap JS mounts do exactly that, as a working example to copy.
