Hugo is fast and just works. However there are certain things you must take into consideration while hosting it.
Till now one thing I came across is the path for css files. Hugo provides template short codes to deal with them.
The templating system cares for empty spaces in the template.
You should be extra careful not to put them.
For example href="{{ .Site.BaseURL }}css/2021.css" and href="{{ .Site.BaseURL }} css/2021.css" are different. Can you see there is a space between }} and css/2021.css in the second example. These kind of things will break the site or theme or both.
However it is a pleasant experience working with this new setup.
Happy Coding.
