Removing padding from map

This map seems to have everything I need, but I would love if I could get rid of the padding on it on the top and sides. There is a little bit on top and a ton on the right side. Is that possible? I would just like to have it run across my entire web page without seeing a background.

Any help would be appreciated.

Thanks!
