Tab styling

I am using the tab shortcode and I am having trouble with the styling of the tabs and the font in the body.

Tabs
The tabs are formatted with dark text on a dark background and are hard to read unless you rollover them. How can I change this and is it possible to have different background colours for each tab?

Body font
The text within the tabs is set to paragraph but it appears to be a different style from the one that is set on my site and so it is too large. How do I edit the styling of this?
Thanks

Thanks
