I just updated my index.html by hand. Because html editors are for babies, real admins directly write and edit the code in a console.
It looks amateurish, of course. Ain’t nobody got time for “stylesheets” and “css” and whatnot. Pure html like we had back in the 90’s. And no one made a fuss back then!
But seriously, I probably should figure out something other than plain html.
