@lyse@lyse.isobeef.org I do agree “the rules of the web”, are far too loose - at least the syntax ones. I do think backwards compatibility is necessary.
As for my website, it might be visually very similar, to how it looked since its creation, many years ago, but it is frequently improved. Features that originally used JavaScript, changed to HTML and CSS components, code simplified, optimised to withstand browser updates and new screen resolutions,… Even a good chunk of the errors on your list, were already addressed and I plan to address the rest soon.
Just find it a bit depressing, that my attempt to bring back some of the old Internet spirit, by making a hidden easteregg page page for this years April 1st, was met with people complaining about April fools day jokes and you insinuating my website sucks.
