Footer - grey area..

Hi all,

Me again... As you were so helpful last time I thought I'd try my luck again.

I'm needing to add a lot of text to the footer of my survey. However, when I preview the survey the footer texts starts on the regular white background and then goes on to grey background as if there is too much text. Is there a way I can extend the regular background to cover all the footer text and not have any grey area, or any other solution?

Thanks
