Trying to target Contact form body (but not head)

I'm using the contact widget and its built-in CSS styler. I've added padding to give it some room to breath in the sidebar with this:

.Contact_form_widget {
padding: 0px 20px 20px 20px !important;

But I don't want padding on the widget title. I've tried targeting various other elements using Firebug, but no luck. What should I target with the padding so that the title remains at the original width ?

You can see the issue in the sidebar here: compare the top widget title to the title of the calendar:
