> Wasm still generates html and outputs it on the screen

Sure it can. More usefully to my point though, it can also use any of a number of C++/Rust/etc. UI libraries to render directly to a buffer or canvas, which is in my opinion a better long term solution for true applications (vs websites).

When you do that you get total layout control with no need for CSS or worrying about browser defaults.

As a random example here is the Rust egui library demo app running in a browser using WASM (no HTML): https://www.egui.rs/#demo

The speed and “native application” feel are hard to replicate in JS/HTML, as they are just not great tools for the job or rich desktop (or desktop-like) applications.
