Changing page background colour to balck

[Malgunn]

Hi there, i wonder if someone can help me.  I am slowly building a site (www.getfabulous.co.uk) and i would some ponters from the more experianced amoung you!

 

1) i would like the individual pages under treatments to be black, however everytime i try to make the pages black, the CSS effects the site as a whole how would i go about this?

2) is it possible to have the menu with just floating text with out the subtle boxes around the text?

3) where is the CSS to be able to change the colour of the grey bar at the bottom of the homepage!?

 

The site although not finished is open for veiw should you need to look and see what i mean.. i have also uploaded an image of what i am attempting to do!

 

I hope this is in the right place..

 

thank you for all your help
