Logo Bridge Problem

Hi I have a problem with bridge update and I fixed it but the logo of my web have implemented in the html code a strange css style:

Because of this my logo is not centered and doesnt have the normal size.

This is the website: http://darioartwork.com

Do you know why that css is there and how can i take it off???

Thanks
