I want to deploy a Hugo template in Google Sites (a free hosting). I currently have a website but I am using the default (new) Google style (I don't link it here because I don't want to reveal my email address).
It is clearly possible to get different styles in Google Sites. Examples of different styles are here, here (this one using the Classic version of Google Sites), and a long list here. But the latter site says:
If you decide to use Google Sites, you should know that it only includes one template with several style options (called "Themes" in Google Sites).
And yet, there are companies offering template services for Google Sites (e.g. here).
