Fullscreen for a certain question in the Survey

Happy New Year!
In one question in my survey, I wish to randomly display few images on the screen and then will ask participant to rearrange them (based on certain rules). For this I need to use the entire available screen of the user.
I have implemented the image displaying part with html/Javascript/css and they are working fine but not on the entire screen - Qualrics just allow me a small window to display/move my images. I tried with div element and css to expand the screen area but no success.
Any help would be appreciated.
Thanks
