I just found out that if I navigate on my website with iOS (iphone and ipad) it shows me this -> https://i.stack.imgur.com/9scRZ.jpg
While if I open it with Android it shows me this one (that is the correct one) -> https://i.stack.imgur.com/lW3VR.jpg
All the images, in different pages, that are as background, have this problem (on iphone), the same for the footer that has a background image too.
It's like if on iPhone all the background images are super zoomed.
I deleted the cache, I checked all my CSS code and I tried to change pictures, nothing happened.
What else can I do?
Thanks for your advices!
Yes, it could behave differently. Since, we could write different css based on resolution or user-agent (safari for ios, chrome for android).
