In Phonegap HTML doesn't resize using app

Question

I have an app for iPhone / iPad Phonegap, and when I rotate the iPad app to the landscape, it doesn't seem to update HTML / CSS anything, so I'm stuck in the black bar to the right of the app. The same thing, if I open the application in the landscape, it looks good, but then it rotates to the portrait, this requires scrolling.

Answer 1

I had to remove height = device-height from my meta tag and it fixed it. Thanks to everyone who helped me!
