Searching for “alternatives to CSS outside of browsers” (f.e. styling systems in GTK, Qt, etc) yields no useful results, as usually they lead to articles on CSS pre-processors or css-in-js.
Are there styling systems that are better than CSS (in your opinion, and even if they do not run in a browser environment)?
I’m curious to know what styling paradigms exist, if any, that some may consider more evolved, more efficient, easier, more robust, or more advanced than CSS.
Or, is CSS the best styling paradigm there is? (In your opinion)
From what I can tell, the GTK and Qt engines have both adopted CSS-based styling mechanisms. For example, Gnome 3 Desktop came out with GTK CSS as the first-class styling mechanism.
If there doesn’t exist anything better (in your opinion), have you ever imagined something better?
