[closed] None zoom after exported html

I would like to add OSM with one marker to my website. I've exported html code from OSM site and I've put it to my code. My problem is that I see the whole Earth with my marker somewhere, without any zoom, and I just have to click + a few times to see my actual location. How can I fix it?

Edit: I've noticed that it happens on Chrome, when I check it on my mobile phone default browser then it's ok
