Personal, but I’d rather learn and own a process.
1. Learn how you can get HTML generated from a human-readable and writer-friendly format, say, Markdown (plain-text). This can be Pandoc, a macOS/Win wrapper desktop UI over Pandoc, and many other tools that do this.
2. Learn the process (and the tools) to upload, or sync to a service that hosts the HTML (CSS+JS).
3. Learn the simple steps of owning of a domain, and updating the DNS to point to the right services, such as Github Pages, CloudFlare Pages, etc.
As you are not dependent on a particular tool/service/platform/company, you can walk out and host your files (the website content) elsewhere.
The post-processing of the raw (Markdown) articles/posts to HTML can be then automated with Static Site Generator if someone is willing to learn a little more on top of the above steps.
Of course, it is a fun and good thing to know HTML but that should be optional to the target of “Run your own website 100% independently.” With Github and Cloudfalre, you can hve it for $0 monthly. If they go kaput or stops free, someone will come up - walk out and walk in elsewhere.
