Remove white border around form

Does anyone know of a way to remove the white border around the form? (without hacking the CSS which would affect all business spaces?)

I mean the border between the menu bar and form, and the left hand side and form, and the right hand side and form.

Rod,

How bad do you want to get rid of that white space?

Yes, it involves hacking a CSS file, but you can always create a new theme and not effect any other Business Space.

Thanks Bob, an excellent idea.

It's a form in an iframe on a website, it looks pretty odd with the white border so I'm keen to get rid of it!
