Content Area Centering

Greetings,

I know that support for the theme (Elegant – Chameleon) is supposed to be through the Elegant website, but this theme was purchased by the former owner of the Yoga centre and I don’t have any id/password for Elegant’s support forum.

Can anybody PLEASE help me in this regard? I am trying to center the Content Area on the Homepage and have checked everything several times, but the three thumbnails & info are still shifted to the left.

Site is Sooke Yoga

Many thanks for any help!
