Have you checked your mobile browser settings if you have not set it to zoom. Also have you tried in some other mobile device to see if issue is there as well ?
While I checked at my own mobile device and found few responsive related bugs which we will be fixing in our coming update.
The one thing I realise is that the video doesn’t play on the mobile version. That isn’t something that has to do with the previous problem but I was wondering if you knew of a quick fix for that
