Everything you say rings true ca 2000 to 2012. Today, CSS and the rendering engines have both improved and converged to such a degree, I’m not sure it’s fair to still criticize them quite so harshly. Of course the cutting edge will temporarily see one rendering engine a few months behind another. But that’s unavoidable unless you prefer a monoculture, which is liable to move slower than slowest of today’s major rendering engines. It’s perfectly normal today to create CSS (and JS) in one browser and find it working flawlessly in another. 10 years ago, you would have called everyone over to your screen to have them witness this miracle.
