Exactly. I haven't done HTML layout since circa 2000. I tried WPF about 8-9 years ago and well, it was just simple to get layouts right. I'm sure there's some reasonable reason for it, I just don't understand why browsers couldn't do similar, or just rip off WPF.

I haven't used WPF in about that time myself, but Android's XML is a roughly similar experience. No idea about iOS's auto layout.
