Creating background for web site

[Chrisj]

I'm using an open source php script for my web site, where the main header, footer and index page are all centered vertically in the browser, with an inch and a half of white space on the left side and right side. How do I add color to the white space on each side?

Use CSS to change the background setting of body.

 

body { background: black; }
