Formatting – Get rid of black box

Hi,

i currently have the plugin installed on this site – https://tokoroa.mobi/

How can i remove the black box from around the Share button? Also is there anyway to reduce the width of the box surrounding the share buttons?

Also something weird happens with the Pin it button in Google Chrome, its fine in Firefox. I am using another plugin called FooBox which is being brought up when the pin it button is selected, is this an error with this plugin or one i should contact the creators of FooBox for?

Thanks in advance
Megan
