At the moment, i'm working on my site. The mobile version is almost done. But if I rotate my screen (smartphone for example) in landscape, it looks horrific. I tried to change it with queries but the result isn't quite nice. Is there a way to lock orientation so that it always stays in portrait-mode?

Edit:

I thought maybe I could do something with the height and the width. So that if the width of the screen is larger then the height, the body should rotate 90 degrees.
