Apply CSS to Constant Contact widget

Trying to insert 10px margin above “submit” button in CC widget.

Installed Constant Contact widget (I do have a CC account) and placed it in the sidebar. Visual anomaly is that the “submit” button butts right up to the “email” data entry window. Search of forums and web unfruitful. Attempts to insert in-line style to the p and div tags enclosing the button not successful. Attempt to add attribute in the p tag (margin-top=”10px”) unsuccessful. The CC-admin-api css seems to come in from the CC site, and haven’t located CC CSS file with class or id info.
