Mobile Safari Viewport - Preventing Horizontal Scrolling?
I'm trying to configure a viewport for mobile Safari. Using the viewport meta tag, I am trying to ensure that there's no zooming, and that you can't scroll the view horizontally. This is the meta tag I'm using:
<meta id="viewport" name="viewport" content ="width=device-width, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" />
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.

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.
