NOTE: This article was originally written in May 2018. Since then, all the themes I looked at have continued to develop, and the new WordPress block editor has been introduced. I’ve added updates throughout the article when I’m aware of them, but these tend to relate to the GeneratePress theme as it’s the one I use myself. That makes this discussion quite biased towards GeneratePress.
I continued to update this article until the end of 2020 but now I have a newer article about building a website with GeneratePress and I would suggest you refer to that instead: ‘Building My “Standard” Demo Site’.
From mid-2024 onwards, I started to look into Full Site Editing / Block themes, and finally decided to switch away from GeneratePress and towards Block themes (see my blog post https://janebwebsitehelp.co.uk/my-blank-slate-website/ )
