Joomla! Template 002066 - Item Support

Hi, I would like to make my background image on the splash page to fill the entire page. it can either be stretched or enlarged to fill. I've searched the css code, but can not figure out what code to add.
I mainly need it to resize dynamically on the splash page for mobile devises or small screens. it shows a white background when resized.
Is there an update available? or I need to report a bug maybe. My contact form is not displaying anymore. I have v. 1.1.0 Dated 2014-03-25
Any ideas?
