TL;DR You can use HTML in Hugo content files (markdown files) by including some (any) markdown code at the top of the page (e.g. an empty header #). Background I recently switched this website’s backend to Hugo instead of HarpJS. I have been using HarpJS for two years and love it. It is a very minimal static website compiler that has support for some great languages, including Pug (formerly Jade), Sass/Less, as well as the usual suspects, including HTML (EJS) and Markdown.
