You clearly have very little understanding of the technologies you're discussing. HTML/CSS is a presentation layer which describes a way of drawing things on a screen. Nothing more. To compare it to Windows is tenuous, and to suggest that "Linux" even has a standard "app runtime" suggests a clear misunderstanding of the Linux ecosystem. Web technologies are a layer below what Android or other mobile platforms expose to developers. They're a platform upon which frameworks can build. I agree that a few frameworks providing UI widgets and allowing easy layout will emerge (as they have in, for example, Bootstrap). I disagree that you can in any way generalise by saying "the web is for desktops" simply because of the history it has.
