CircleSpace Theme – adding max width to slider

Hi There – I’m a newbie to all this. I finally got my site up with help – paolinamilana.com – but it’s not looking so great on my iphone because of the slider. I added the mobile plug-in WP Touch. No help. I then thought maybe I could just remove the slider from the mobile?? OR I was thinking of altering the CSS (as I’ve read) to have a “max-width” instead of defined…but I can’t figure this out. Any help?
