Verity Free version not resizing correctly on cell phone (possibly others also)

http://www.psdkennels.us I have installed Verity free my issue is with the "Home or Front page" basically from what i see the theme does not generate a front/home page automatically? you can select a page to show there or another option is Hero (posted as home or front page?) what is the difference? I have tried both options a select a page to show b hero content select a page to show I think it is just not resizing....not resizing correctly for mobile Also header shows up correctly on laptop is not resizing for mobile sometimes not showing up at all.... sometimes when i go back to pages they don't display correctly even in WP page view. what am i missing? Many thanks Angel
