I commend you. I am with Kyle Simpson (of the You Don't Know JavaScript fame) here—too often people don't even try to learn about the stuff they are using and are surprised by the behaviour which is clearly stated in the specification. This is true for JavaScript, but this is especially true for CSS. I think it is one of the least respected technology, devs don't spend much time and effort in learning it and then complain about it being a mess and not making sense. So if anyone is tired at throwing stuff at the wall and seeing what sticks just go and read the specs. It's much easier now than back in the days of IE5/6, no grid and no flexbox.
