Page moves after selecting 'test area'

I have the makings of a Mobile Web App, but have an issue with the page moving after selecting a text area. It may be an IOS thing. What happens is after selecting the text area, adding some content, after selecting ‘done’ in the IOS keyboard, the whole page shifts up and out of the way.

Trying to have this be a one page App that has no vertical or horizontal scrolling.

This is only styled for mobile, it will look broken in desktop view.

Thank you for any help!!
