Not on Firefox mobile it works but elements do not feel like they display right. And you can scroll down to see hover answers, which had no questions.

I found out what those were exactly since I jumped into desktop mode, which had even more noticeable issues.

I hate mobile first design choices for adaptive interfaces, since they in a lot of cases, aren't suited for either platform

Most of the UI animations are laggy in my browser (Firefox 60).

It's not working properly at all! [1]
