Hi,
It most certainly is possible. We have a good example of this here. To do this you will need to enable the "Enable Per Question CSS Classes" option on the form and add CSS classes on the individual inputs you put on the form. If you look at the markup and CSS for the page I linked above, you will see how it all ties together. This example actually uses another option as well; "Flatten Pages As Groups," which allows you to have groups of inputs.
Just post any questions you have and we'll be happy to help.
Hope this helps,
Joe Davis
