I'm using a Twenty Eleven child theme, with a static page as my home page. My site looks good on my wife's iPod Touch, except that the posts page/blog page renders much more narrow than the other pages.
The site is here:
When I view the home page and About Me page, they fill up the whole iPod screen (whether I'm holding it horizontally or vertically -- the pages expand properly, is the point). But when I go to the blog page, the content only takes up a bit more than half the screen, with the background taking up the right side.
Edit: Well, it's not my child theme. I just switched my theme to Twenty Eleven to see how that looked, and I got exactly the same issue. Is this just a bug in the theme? I don't have many plugins, and none of them do anything that would make me suspect they were the culprit.
