Difference in the grid of the system viewer and published site

Hi there,

I’m building a website and I thought that it worked fine, until I opened the published site. If you view it in a very wide viewport the images doesn’t aline well anymore. Can someone please explain to me why?

Here is the read only, and the published link.
