Me, 5000+ pages of html and css. I had some JavaScript once but later I didn't need it.
But before talking about encoding, it behooves us to have a clear assessment of the goal: for me, I'm making a document. Though obviously silly, you could print my website on paper (with numerous formatting atrocities I suppose).
In the early oughts, when "everyone" was looking for a CMS or whatever to add to the complexity of their lives, I did too, tried s couple, came to my senses and realized that all I was doing was some late-20th fancy writing, and images and links and documents, learning my own personal subset of css was far more than enough.
Of course YMMV, and other people, other needs. But I think too many just embrace new tech thinking they'll be considered backwards or something if they don't.
