CSS Style Align

1

I have the following CSS style to control the layout of a html page:

body {
	background-color: white;
	background: url(images/bg.jpg) top center; background-repeat:repeat-y;
   [color=red] margin-top: 0pt;
[/color]	
	scrollbar-face-color: #ffffff;
	scrollbar-highlight-color: #cccccc;
	scrollbar-shadow-color: #999999;
	scrollbar-3dlight-color: #FFFFFF;
	scrollbar-arrow-color: #999999;
	scrollbar-track-color: #ffffff;
	scrollbar-darkshadow-color: #666666;
}

In the HTML page I have one main table for all the other content. I want the table to align in the centre with a margin of 0pt on top. The margin of 0pt is working because of the margin-top code in my CSS style, but I don’t know how to align the table horizontal in the centre within this body Style.

I want the alignment insite the body code, just like the background-image part.

How do I do that?

Thanks in advance
