How to change css in the breadcrumb nevigation

[pralay]

Hi all,
I want to change the css of the breadcrumb nevigation.
Can anyone tell me how to do it?

The breadcrumbs (e.g. Products >> Maxton portable), Header (e.g. "Our
  Products") and Subhead (e.g. "Water ionizers, accessories and supplies
  for healthy living") are still too far apart.
I want to collapse that space.

I want also to  make the
  subheader a slightly lighter shade of grey (so the header will stand
  out more when they are closer together).


It's urgent.

Do you have a link to the page?...
