Responsive website on iPhone – unwanted white space on rotate from landscape to portrait

Question:

I am creating a responsive website, and have just noticed a strange behaviour in my content pages when viewed on the iPhone. It scales correctly when loaded in portrait mode, and also when rotated to landscape. However, when rotating back to portrait the page seems to shift left, or not zoom correctly, and there is a strip of white space down the right-hand side. This white space also seems to be present on first loading in portrait as the user can swipe the page left

On my iPhone when I load the page, it seems to look okay:

But I can scroll horizontally, so that it looks like this (this is as far to the right as I can go:

When I swing it into landscape view, the page renders as expected, locking the horizontal scroll position.

I’m trying to figure out how to make this page not scroll horizontally at all. Is it possible that I’ve got some page element pushing the content out? I wouldn’t even expect that to be possible with a correct viewport set, but I’m grasping at straws here.

 

Answer

Is it possible that I’ve got some page element pushing the content out?

Yes, that is indeed the case. The viewport setting only defines the visible viewport area but does not deal with turning off sideway panning.

So, in order to avoid this from happening, set an overflow:hidden on the element that contains your content, or else, avoid elements from overflowing.

NB: other mobile browsers also support the viewport meta tag since a while, so you’ll want to test in those as well.
