Unless other solution is available or suggested.
Trying to do an app Responsive using Screen width as value to assess.
This works fine - However -
If the Screen is an Ipad or eqv i would like to
Set the size of the font in Input text boxes and which do not have the “Font Size” available as block.
Worth saying is also that i am using text box because i cannot use a normal Label Block since it is not possible to Scroll (Which i can with the Input text box.
Should not be that hard (!) 
to fix either of those right ??
Excited to hear thought on this, or if there is a workaround
Cheers
Stefan
