“Nice” is entirely subjective. I think my site is nice, but someone else might think it’s garbage.

I use Hugo to generate my site. It’s not wysiwyg, but it supports markdown for pages, which is even simpler than html. It also has a live server mode, where you can see changes immediately.

The community has a created whole gallery of themes (templates) that you can use. It might be worth looking through the gallery to see if you think any of them look “nice” to you.
