I am relatively new to Hugo. Hopefully there is a quick fix to the following issue:
I cloned https://github.com/alanorth/hugo-theme-bootstrap4-blog to the theme directory. I copied the config file and placed it in the website’s parent folder. I also copied the content from the ‘examplesite’ folder into the main theme folder.
I ran the Hugo Server to generate the website on localhost:1313. It is showing HTML only. No CSS. Website below:
I’m not sure whats wrong with css in your project, but it rendered prefectly after replace style.css in your project with fresh style.css from the original theme.
