Styling A Fieldset - 7 Buttons in a row.

Styling A Fieldset - 7 Buttons in a row.

Hi, I have a fieldset on my page that contains 7 radio buttons horizontally.  I am stuck however on how to style it as I want the buttons to be red and when pressed change to blue.

Also I want a white border around the fieldset and not each button.

Example.

---------------------------------
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |            : Horizontal role of buttons in the field set.
---------------------------------

Thanks in advance,
Paul.
