If you actually read the README.md file, the first few lines say that there are hosted versions available that you can view directly in your browser. I also mentioned this in another comment. I don't know what else you want...
Well, then something's wrong. I click on different pages in the documentation and the whole page gets rerendered. Seems like it's not delivering what's promised.
It's more like ReactJS/SolidJS (but in Rust) rather than a component library like Bootstrap. Although I definitely agree the home page can do a much better job of explaining this.
That was the main point at beginning. They aren't showing, so kind of leaving it up to you to go dig through the manual. Like reading the manual is not a demo.
They aren't giving any incentive to cause someone to waste time on them.
I wish they said that on the homepage. I assumed it could render to the desktop or something, and I had to read tea leaves to figure that out.
