问题
After upgrading my iOS devices to iOS 8.3 I noticed some weird behavior with the meta viewport. If I set the viewport with fixed width(a number such as 640, other than device-width) and rotate my device while I am on a webpage, the whole content will get smaller and eventually the browser will crash.
<meta name="viewport" content="width=640, initial-scale=1.0,user-scalable=no, target-densitydpi=device-dpi">
Is there a way to fix this issue?
