Website doesn't customize on mobile

I just started my website and at first it worked perfectly on mobile, but now when I visit my website on my phone, it looks weird. Only part of the background can be seen if you zoom out. The rest stays blanc. I think it is because of Google Fonts, although at first this worked perfectly also on mobile. I am not sure though. Can you help me?
