also it does things weirdly and surprisingly - like right in the first codepen sample when she put width and height to be 100% of the viewport but the svg engine decided not to stretch it... ugh. and that ignoring browser specific issues, for example svg and css filtering don't work on edge/ie11 but nice hacks I guess. the real takeaway are probably svg animations, those can make cool stuff without the keyframe weirdness.
