Background image in pages

[busymum]

How can I put a different background in the product pages so that the homepage and other e-z pages, for example, have a different background to the product pages. I mean the background in the whole page,
body {
margin: 0;
font-family: verdana, arial, helvetica, sans-serif;
font-size: 62.5%;
color: #000000;
background-color: #ffffff;
margin-top: 12px;
background-image: url(http://www.site.com/shop/images/background.gif);

for example.

Thanks.

Thanks. So if I create this: page_name.css // changes to one page

Sorry, I'm confused. The pages don't actually have names as the info is called in using php. So, what do I call page_name.css in order to get a different background on the product pages? Sorry if it's obvious!

Load the page and check the address in the browser i.e.

/index.php?main_page=page&id=4
