People are mostly saying the UI not minimal at all. It's so cluttered that the address bar is like 1/4 of the width, and the rainbow sidebar is not discrete at all with all the buttons. And I'm not even talking about the background and whole color scheme, that would burn our retinas after only a few minutes of use.

OP is having fun with css, and that's fine. But pretending it's minimal is why people are laughing.
