Hello,
I had the problem with both horizontal and vertical scroll bars. Managed to get rid of the horizontal scroll bas using the parameters ~itsmobileelemfactor and ~itsmobileelemunits but the vertical scroll bar is still there. As our transactions are developed internally, I managed to sqeeze the screen elements but still the vertical scroll bars are there.
I am testing with Intermec CK3 device with Intermec Browser.
I was going thru this forum and someone has suggested to modify the CSS.
Can someone help me which html parameters are required and under which css class e.g. font size, line-height etc to reduce the overall screen size? I am not good in HTML. 
Thanks in advance.
Regards
Narottam
