How do I adjust the padding around these widgets in the header area?

Hi,

I need to adjust the spacing between items in the header so that they look like they have the same space between them.

I see that some of the code on these widgets is:

#black-studio-tinymce.widget.widget_black_studio_tinymce 280px x 76px

Is there anyway to make this 100% height and width, so there is no space around the widget item?

Thanks,

Rebecca
