This is the situation
-I have a website with 3 variants, main (1920), mid (960), mobile (480).
-I use preview website to see how the website looks when I resize the window to scale down to the next varient
-It scales down without any problems in the Xara website preview and in Edge and Explorer but not in Chrome
-In Chrome when I resize from my 1920px page to my 960px page, chrome does not change the page width
-It looks as if chrome is keeping the 1920px width from the main page for my 960px width mid page
-So my mid page ends up being there, but on a 1920px page, if I scroll over to the right I see all this blank space

I've tried searching for similiar problems here and on google but did not find anything.
I've double checked the page width for the 960px varient, and I've locked it down to 960px
I've tried moving the page around in various ways, what gets me is that its only chrome this happens in

Any advice would be huge, thanks.
