Twitter icon changes

On my site in development I am using the plugin, but it seems as though it conflicts with my theme css. See this screenshot I would like in this instance to remove the . and only have the icon in that one columne, and have the icon align correctly.

Do you have any insight? url is: http://www.mynewdev.com/puppy2/test-food-ordering/

It is in the footer at the bottom.

Thank you very much.
