99% of the new css features are not known or just unknown, because it's a hassle to use them. Syntax is just plain braindead. Just look at animations, grid and flexbox. These are supposed to fix lots of CSS2 era problems, and they do so in a mindboggingly shitty way. I mean anyone, who was responsible should be shot. And since it's a standard, it won't change for years to come.

So the idiots who established these new, contrived CSS syntaxes literally making people go on all fours, because... well, because they have the power to release such a mountain of shit.

Microsoft's Internet Explorer bullied every web developer for decades. Now Safari earned the honour of becoming the bully amongst web browsers, with their we just couldn't care less attitude. They do things here and there just a tad bit different, because, well, they are Apple, and everyone can fuck off. Like their fullscreen media query implementation, or the blur rendering outside viewport shenanigans just to name a few of their idiotic choices.

And Chrome... we need to wrestle away the browser from Google. The sooner, the better.
