Mobile dynamic height content

I am trying to create a Videoask like app for mobile, using ziggeo, and Zerocode’s plugin Newvideoplayer @devon.
It seems that for any element that is not a bubble element and maybe could be hacked with css i cannot hope to get full height for my app on mobile. The player’s and recorder’s always get cut off in some sort of way.
Does anyone have any idea how to actually make dynamic height of elements so they fit to the entire mobile screen with a native “feel” to it?
