I'm asking the same question!

No doubt the very loudly opinionated not-web-dev community, who have So Much To Say about web devs and web tech, have produced an uncontroversial, perfect layout system, styling system, and language to produce the replacement for this awful web tech. Where is it? What is it? Please provide (the better version of) a hyperlink to the docs.

There's decades of UI frameworks where the structure of the elements/widgets dictates the layout. HTML/CSS doesn't do that, because it is clearly made to style text documents, not UIs.

So yes I will argue that Qt6 and GTK are better than flexboxes.

Because you asked for it, here's some documentation to a UI framework which I believe to work better than the web stack: https://doc.qt.io/qtforpython-6/PySide6/QtWidgets/index.html
