When I open the website http://www.stuttmann-karikaturen.de/karikatur/6358 in Chrome, make the browser window as narrow as possible and then swipe the image to the left with the mouse, everything works as it should - the title stays in the center and the image moves:
If I switch to iPhone 6 view mode and do the same, the title moves to the left as well (just as it does on a real iPhone):
I don't know enough CSS to find the reason behind that (I didn't write it, that's my excuse).
I checked if on of the containing elements (1, 2 in image below) is too wide, but as far as I can tell it fits the phone width exactly (both are set to 375, matching the width of the iPhone view in Chrome) (3):
So it seems that neither
<div id="container">
nor
<div id="wrapper">
are responsible. I guess there is a difference between the behavior of swiping in a small browser window and the one in an iPhone. How can I turn that off?
Additional note: the owl-carousel is just to add this gallery functionality to jQuery. I did not post additional code because (a) the issue is visible online and (b) there's a lot code involved that could be responsible so I post it on request.
Try to make a
overflow-x: hidden
on the body, it will fix your problem.
This bug is present because image width in your slider is too large
